Cellulose acetobutyrate

Cellulose acetobutyrate with high levels of butyric acid and medium MW is used as a leveling agent. It is typically used in wood coatings and automotive coatings. The low MW modifications are recommended for unsaturated polyester resins and UV-curable varnishes.

Other Polymers. Besides polycarbonates, poly(methyl methacrylate)s, cycfic polyolefins, and uv-curable cross-linked polymers, a host of other polymers have been examined for their suitabiUty as substrate materials for optical data storage, preferably compact disks, in the last years. These polymers have not gained commercial importance polystyrene (PS), poly(vinyl chloride) (PVC), cellulose acetobutyrate (CAB), bis(diallylpolycarbonate) (BDPC), poly(ethylene terephthalate) (PET), styrene—acrylonitrile copolymers (SAN), poly(vinyl acetate) (PVAC), and for substrates with high resistance to heat softening, polysulfones (PSU) and polyimides (PI). 

Plasticizers can be classified according to their chemical nature. The most important classes of plasticizers used in rubber adhesives are phthalates, polymeric plasticizers, and esters. The group phthalate plasticizers constitutes the biggest and most widely used plasticizers. The linear alkyl phthalates impart improved low-temperature performance and have reduced volatility. Most of the polymeric plasticizers are saturated polyesters obtained by reaction of a diol with a dicarboxylic acid. The most common diols are propanediol, 1,3- and 1,4-butanediol, and 1,6-hexanediol. Adipic, phthalic and sebacic acids are common carboxylic acids used in the manufacture of polymeric plasticizers. Some poly-hydroxybutyrates are used in rubber adhesive formulations. Both the molecular weight and the chemical nature determine the performance of the polymeric plasticizers. Increasing the molecular weight reduces the volatility of the plasticizer but reduces the plasticizing efficiency and low-temperature properties. Typical esters used as plasticizers are n-butyl acetate and cellulose acetobutyrate. 

This isoindoline nickel complex pigment is mainly recommended for the coloration of metallics and effect coatings, especially for water based systems. P.R.271 affords yellowish to medium red shades, providing a bright flop in metallics. Alkyd/melamine resin systems may safely be overcoated and withstand exposure of 140°C for 30 minutes. The flow properties of P.R.271 in these systems and in polyester cellulose acetobutyrate base coat systems are good, but there is a certain tendency to flocculate.

Natural products and transformed natural products can also be used as binding agents for packaging applications. These are shellac, dammar gum, dried unsaturated oils (linseed oil), rosin and hydrated esters of rosin, cellulose acetate and propionate acetate, cellulose acetobutyrate, cellulose nitrate and ethyl cellulose.

The photochromic response of spirooxazines was shown to be somewhat affected by the substituent on the indolino nitrogen5 (Table 2.2). For various 1-alkyl-5,6-dimethyl-9 -methoxy NISOs in cellulose acetobutyrate, photochromic activity increased in the order 1-methyl < 1-ethyl < 1- n-propyl < l- -butyl. However, the effect was not straightforward.

It is used mainly in the manufacture of cellulose acetobutyrate, the preferred cellulose ester for molding powders. Cellulose acetobutyrate (CAB) and cellulose acetate (CA) are commonly used for eyeglass frames. Cellulose acetobutyrate is used for automotive applications such as steering wheels. 

Cellulose esters such as cellulose acetobutyrate and cellulose propionate, which originally required plasticizers, are today blended with EVA and EVA graft polymer, respectively, to convert them into thermoplastic products (47).

The polyolefin melt is forced through an annular slot 3 of extrusion head 2 and is blown out into a hose. A solution of Cl that is easily volatile in PI is fed onto the site over the mandrel. The Cl solution dissolved in the varnish based on PVB, CEVA or cellulose acetobutyrate is forced to the surface of a diaphragm Table 2.11. The varnish is poured over the inner surface of the rising hose so as to avoid contact between the lower edge of the annular flow of varnish and the Cl layer. The varnish contacts the colloidal solution of polyolefine with Cl formed in the hose surface layer. Above the solidification line A-A the colloidal solution decomposes into phases and a jelly-like layer is formed. Just in this layer the inhibiting liquid is enclosed in the polymer matrix pores that are thermodynamically compatible with the varnish. The varnish diffuses into the pores and, on setting, forms on the inner hose surface an inhibited varnish coat embedded in the porous layer.

Automotive Finishes. Important industrial automotive topcoats are produced from alkyd resins. Two-coat metallic finishes consist of an acrylic clearcoat and a metallic basecoat. Solventborne basecoats are generally composed of cellulose acetobutyrate and a low molecular mass, branched polyester resin which exhibits high reactivity with precondensed melamine cross-linking resins.

Dichloromethane is used as a noncombustible solvent and extractant for oils, fats, waxes, fish oil, etc. from industrial and animal products, as well as caffeine, hops, castor oil, cocoa butter, and ethereal oils from substances of plant origin. It is used in the deparaffination of petroleum and the azeotropic dewatering of solvents. Dichloromethane is a constituent of paint-removal pastes and baths, but is increasingly being replaced by aqueous systems. It is used as a solvent in the production of cellulose-acetate-based or cellulose-acetobutyrate-based films and is employed industrially in the leather, metal, rubber, adhesives, and plastics industries. 

Methylbenzyl alcohol [98-85-1] (1-phenyl-ethanol, 1-phenylethyl alcohol, phenyl-methylcarbinol) is an almost colorless, neutral liquid that has limited miscibility with water and a weak, bitter, almond-like odor. It has a high solvency for alcohol-soluble cellulose nitrate, cellulose acetate, and cellulose acetobutyrate for many natural and synthetic resins and for fats and oils. In contrast to benzyl alcohol, it is miscible with white spirit. 

Isobutyl acetate [110-19-0] is a colorless, neutral liquid with a pleasant, fruity odor. It is miscible with organic solvents, but immiscible with water. Isobutyl acetate has a high solvency for cellulose nitrate, colophony, damar resin, ketone and ketone-formaldehyde resins, maleate resins, urea and melamine resins, and phenolic and alkyd resins. Polymers such as polystyrene, poly(vinyl ethers), poly(vinyl acetate), polyacrylates, chlorinated rubber and vinyl chloride copolymers, as well as fats, greases, and oils are readily dissolved. Postchlorinated poly(vinyl chloride) is less soluble. Polyisobutene, cellulose ethers, polymethacrylates, poly(vinyl butyrals), natural rubber, and manila copal are swollen. Shellac, cellulose acetate, cellulose acetobutyrate, poly(vinyl chloride), and poly(vinyl formal) are insoluble. 

Ethylene carbonate [96-49-1] is soluble in water and organic solvents and solid at room temperature. It is a high boiler that is insoluble in gasoline and turpentine oil. It has a high solvency for polyacrylonitrile, polyamides, glycol terephthalates, and poly(vinyl chloride). Cellulose nitrate and cellulose acetobutyrate only dissolve in the presence of alcohol or esters. Ethylene carbonate is used for polyacrylonitrile spinning solutions.

Cellulose acetate is the most well known plastic with a cellulose base. Others are cellulose acetobutyrate and cellulose propionate. Cellulose hydrate may be used as a vulcanized fiber. Cellulose may be identified fairly simply. Dissolve or suspend a sample in acetone, react it with 2-3 drops of a 2 % solution of a-naphthol in ethanol, and carefully introduce a layer of concentrated sulfuric acid under this. At the phase boundary, a red to red-brown ring forms. In the presence of cellulose nitrate, a green ring forms. Sugars and lignin produce interference. For differentiation between cellulose acetate and cellulose acetobutyrate, it is usually sufficient to examine the vapors produced by dry heating of the sample. The acetate smells like acetic acid the acetobutyrate smells of both acetic acid and butyric acid (like rancid butter).
