Polymer resin polyvinyl butyral

Epoxy resins may be blended with certain vinyl polymers to improve the impact strength and peel strength of the adhesive. Polyvinyl acetals, such as polyvinyl butyral and polyvinyl formal, and polyvinyl esters are compatible with DGEBA epoxy resins when added at concentrations of 10 to 20% by weight. The addition improves the resulting impact resistance and peel strength of the cured adhesive. However, temperature and chemical resistance are sacrificed by the addition of the low-glass-transition-temperature vinyl resins. 

Butanal is used in the manufacture of rubber accelerators, synthetic resins, solvents, and plasticizers. -Butyraldehyde is used as an intermediate in the manufacturing of plasticizers, alcohols, solvents, and polymers (such as 2-ethylhexanol, -butanol, trim-ethylolpropane, -butyric acid, polyvinyl butyral, methyl amyl ketone). It is also used as an intermediate to make pharmaceuticals, agrochemicals, antioxidants, rubber accelerators, textile auxiliaries, perfumery, and flavors. It has no therapeutic use at the present time.

In the waterborne phenolic adhesives, a new dispersion system (98) has been reported. This system uses the solubility of some thermoplastics in phenol, and the subsequent polymerization takes place upon the addition of formaldehyde, an emulsifier, and water. The dispersion is then formed in situ. The versatility of this process is indicated by the use of many polymers with a wide range of properties, e.g., polyvinyl formal, polyvinyl butyral, acrylonitrile-butadiene copolymer, bisphenol-A resins, polyvinyl acetate, polycarbonate, polymethyl methacrylate, and nylons. 

Some other polymers such as aromatic and aliphatic hydrocarbon resins, high MW alkylated amino resins, polyvinyl ethers and polyvinyl butyrals are utilized for the purpose of enhancing leveling. They are not marketed as leveling agents but are used in specialty products. 

Vinyl Resins n (1934) According to common chemical nomenclature, all resins and polymers made from monomers containing the vinyl group, H2C=CHX. In the chemical literature, polystyrene, polyolefins, polymethyl methacrylate and many other styrenic, ethenic, and acrylic copolymers are classified as vinyls (Mishra, M. K. M., and Yagci, Y., Handbook of Vinyl Polymerization Marcel Dekker, New York, 1998). In the plastics literature, the above materials are given their own classifications and the term vinyl is restricted to compounds in which X, above, is not H, a hydrocarbon radical, nor an acrylic-type ester. In daily use, the term vinyl plastics refers primarily to Polyvinyl Chloride and its copolymers, and secondarily to the following Polyvinyl Acetal, Polyvinyl Acetate, Polyvinyl Butyral, Polyvinyl Dichloride, Polyvinyl Formal, Polyvinylidene Chloride, Polyisobutylvinyl Ether, and Poly(l-Vinylpyrrolidone). 

EFFECT ON POLYMER AND/OR OTHER ADDITIVES Silicone-polyvinyl butyral copol5Tner resin can be obtained by reacting a silicone modifier containing at least one free isoeyanate group with a polyvinyl butyral resin. ° This eopolymer can be added to the base resin to function as an internal release agent. 

Reaction of PVOH with butyraldehyde or formaldehyde gives products of commercial significance. Two of these are polyvinyl butyral (PVB) and polyvinyl formal. These are examples of useful resins made by modifying modified polymers. The latter is made into a varnish for coating wire and cable, and the former is extruded into sheet. Large quantities of PVB are used for the energyabsorbing layer in auto windshields. 

Adhesives which incorporate phenol-formaldehyde resins are much used as structural adhesives for metals. They comprise the original polyvinyl formal/PF, and polyvinyl butyral/PF together with nitrile phenolics and epoxy phenolics. The ratio of non-phenolic polymer to the PF resin in the structural adhesives determines the morphology of the material, whether it is two-phased, and which phase is continuous and which discrete. This, in turn, influences the flexibility of the...

In most widely used two-polymer adhesives, the thermosetting component is phenolic. Phenolic resins are generally compatible, although not easily miscible, with a number of thermoplastic polymers. Particularly good compatibility is demonstrated between conventional alcohol-soluble phenolic resins and polyvinyl esters and acetals. Epoxies are important in two polymer adhesive systems. The most important thermoplastic components are the polyvinyl acetals (polyvinyl formal and butyral) and synthetic rubber, particularly nitrile rubber. Soluble nylons are also an important class. ...
