Vinylesters

Modified Bismaleimides. Bismaleknide resins may be further modified and blended with other thermoset resins or reactive diluents to achieve either specific end-use properties or processibiUty. Thermoset resins that can be used for modification are unsaturated polyesters, vinylesters, cyanate esters, and epoxies. [Pg.30]

The characteristics of the three most common thermoset resin systems used in pultrusion are compiled in Table 11.2 [3]. It is noteworthy that unreinforced polyesters and vinylesters shrink 7-9% upon crosslinking, whereas epoxies shrink much less and tend to adhere to the die. These epoxy characteristics translate into processing difficulties, reduced processing speed, and inferior component surface finish. It is normal practice to use resin additives to improve processability, mechanical properties, electrical properties, shrinkage, environmental resistance, temperature tolerance, fire tolerance, color, cost, and volatile evaporation. It is normally the resin, or rather its reactivity, that determines the pulling speed. Typical pulling speeds for polyesters tend to be on the order of 10-20 mm/s, whereas speeds may exceed lOOmm/s under certain circumstances. Apart from the resins characterized in Table 11.2, several other thermosets, such as phenolics, acrylics, and polyurethanes, have been tried, as have several thermoplastics (as will be discussed in Sec. 11.2.6). [Pg.324]

Addition poly(imide) oligomers are used as matrix resins for high performance composites based on glass-, carbon- and aramide fibers. The world wide market for advanced composites and adhesives was about 70 million in 1990. This amounted to approximately 30-40 million in resin sales. Currently, epoxy resins constitute over 90% of the matrix resin materials in advanced composites. The remaining 10% are unsaturated polyester and vinylester for the low temperature applications and cyanate esters and addition poly(imides) for high temperatures. More recently thermoplastics have become important and materials such as polyimides and poly(arylene ether) are becoming more competitive with addition polyimides. [Pg.167]

CTBN and derivatives are also used in unsaturated polyester and vinylester resins but with less success. Studies have shown that the elastomer additive alone is very often immiscible in a polyester resin. [Pg.242]

Henke et al78 reported the resolution of 2(4-isobutylphenyl)propanoic acid 59 (ibuprofen) by transesterification of its corresponding vinylester 61 using lipase from Candida antarctica. Depending on the nucleophile, the vinylester 61 was recovered with 8-99% ee while the alkyl ester 62 or the free acid 59 is recovered with 16-75 % ee. [Pg.213]

Vinyl chloride can be copolymerized with a series of monomers Vinylidene chloride, trans-dichloroethylene, vinylesters of aliphatic carboxylic acid (C2-C18), acrylic acid esters, methacrylic and/or maleic acid as well as fumaric acid with mono-functional aliphatic saturated alcohols (Cj-C18), mono-functional aliphatic unsaturated alcohols (C8—C18), vinyl ethers from mono-functional aliphatic saturated alcohols (C i-Cis), propylene, butadiene, maleic acid, fumaric acid, itaconic acid, acrylic acid, methacrylic acid (total < 8 %) and N-cyclohexylmaleinimide (< 7 %). [Pg.31]
