Butadiene rubber chlorination

Several examples of cationic grafting have been reported in the literature [40, 41]. Polymer chains having labile halogen atoms in combination with various Lewis acids have been used. Examples are polychloroprene, poly(vinyl chloride), chlorinated styrene-butadiene rubber, chlorinated PB, etc. The monomers involved in the grafting reaction include isobutylene, styrenes, THF, alkyl vinyl ethers, etc. [Pg.17]

Butyl phenolic resin is a typical tackifier for solvent-borne polychloroprene adhesives. For these adhesives, rosin esters and coumarone-indene resins can also be used. For nitrile rubber adhesives, hydrogenated rosins and coumarone-indene resins can be used. For particular applications of both polychloroprene and nitrile rubber adhesives, chlorinated rubber can be added. Styrene-butadiene rubber adhesives use rosins, coumarone-indene, pinene-based resins and other aromatic resins. [Pg.597]

Pandey et al. have used ultrasonic velocity measurement to study compatibility of EPDM and acrylonitrile-butadiene rubber (NBR) blends at various blend ratios and in the presence of compa-tibilizers, namely chloro-sulfonated polyethylene (CSM) and chlorinated polyethylene (CM) [22]. They used an ultrasonic interferometer to measure sound velocity in solutions of the mbbers and then-blends. A plot of ultrasonic velocity versus composition of the blends is given in Eigure 11.1. Whereas the solution of the neat blends exhibits a wavy curve (with rise and fall), the curves for blends with compatibihzers (CSM and CM) are hnear. They resemble the curves for free energy change versus composition, where sinusoidal curves in the middle represent immiscibility and upper and lower curves stand for miscibihty. Similar curves are obtained for solutions containing 2 and 5 wt% of the blends. These results were confirmed by measurements with atomic force microscopy (AEM) and dynamic mechanical analysis as shown in Eigures 11.2 and 11.3. Substantial earher work on binary and ternary blends, particularly using EPDM and nitrile mbber, has been reported. [Pg.302]

Green rubber is sometimes used as a primary or secondary binder in disk and drum formulations. Nitrile, styrene-butadiene and chlorinated rubbers have been used for this purpose. These rubbers are intimately mixed with curatives and other ingredients in intensive mixers. [Pg.1078]

Grafting from, exploits the active sites, which exist or can easily be generated on a polymer. Halogenated polymers are most frequently used for this purpose poly(vinyl) chloride), polychloroprene, chlorinated EPDM, chlorobutyl rubber, bromobutyl rubber, chlorinated polybutadiene, chlorinated butadiene-styrene copolymers etc.145).

Chlorine-containing rubbers based on the polymerisation of chloro-prene [reaction (1.4), R = Cl] are speciality polymers with good resistance to organic solvents and chemical reagents.

The fluorinated rubbers are exceptionally good for high-temperature service, but they are below silicones in this respect. They resist most of the lubricants, fuels, and hydraulic fluids encountered in aircraft a wide variety of chemicals, especially the corrosive variety and also most chlorinated solvents. They have good physical properties, somewhere near those of styrene butadiene rubber (SBR) at the higher hardness levels. FKM is valnable in automotive use for its extreme heat and oil resistance and is on a much higher level in this respect than the acrylic elastomers. It has weathering properties snperior to those of neoprene. However, fluoroelastomers are relatively expensive. [Pg.215]

Polystyrene resins are made from polymerized styrene and have good insulating power. Synthetic rubber, known as styrene-butadiene rubber or chlorinated rubber latex, can be used in paints for floor coverings or tank linings (Fischer and Adams 1990). [Pg.665]

Halogenated butyl rubber greatly extended the usefulness of butyl rubber by providing much higher vulcanization rates and improving the compatibility with highly unsaturated elastomers, such as natural rubber and styrene-butadiene rubber (SBR). These properties permitted the production of tubeless tires with chlorinated or brominated butyl innerliners. The retention of air pressure (5) and low intercarcass pressure (6) extended tire durability. [Pg.900]

Several strategies have been reported to improve the compatibility of NR/ EPDM blends, including the addition of a third component with low molar mass or a third polymer, sueh as polybutadiene (BR), styrene butadiene rubber (SBR), chlorinated rubber, chlorosulfonated PE or polyvinylchloride (PVQ, the incorporation of an accelerator moiety in the less unsaturated phase, and the functionalization of EPDM with maleic anhydride. ...

The chemical properties of the block copolymers are similar to those of unvulcanized styrene-butadiene rubber. Thus the block copolymers are soluble in a range of solvents, including chlorinated and aromatic hydrocarbons, esters and ketones. [Pg.439]

Acrylonitrile-butadiene rubbers are used almost invariably on account of their resistance toward non-polar solvents such as petrol and oils. The vulcanizates are, however, swollen by aromatic hydrocarbons and polar solvents such as chlorinated hydrocarbons, esters and ketones. [Pg.440]

Butadiene rubber is not resistant to mineral oils and fuels. However, butadiene rubber is resistant to alcohols, esters, glycols, and non-oxidizing acids. Butadiene-rubber is not resistant to chlorinated hydrocarbons, including vegetable and animal fats and oils. Water absorption is low [697]. [Pg.810]
