Acetophenone based bisphenol polyarylate resin compositions, their formation and molding.

摘要

A fully compatible moldable polymer composition which exhibits a single phase and a single glass transition temperature value on blending, said composition comprising (A) a copolyester of 30-70 mole % isophthalic acid, 70-30 mole % terephthalic acid and a bisphenol selected from 1,1-bis(4-hydroxyphenyl)-1-phenyl ethane, 1,1-bis(4-hydroxyphenyl)diphenyl methane, 1,1-bis(4-hydroxyphenyl)fluorenone and mixtures thereof and (B) a copolymer of more than 60 up to 87 mole % monovinyl aromatic monomer and less than 40 down to 13 mole % N-arylmaleimide. The composition may be rubber-modified.
