Claims
- 1. A moldable polymer composition comprising:
- (a) from about 1 to about 99 weight percent of a polyarylate containing in mole percent from about 15 to about 35 isophthalic acid or a reactive derivative of isophthalic acid, from about 15 to about 35 terephthalic acid, or a reactive derivative of isophthalic acid and about 50 of at least one polyarylate material selected from the group consisting of 1,1-bis(4-hydroxyphenyl)-1-phenylethane; 1,1-bis(4-hydroxyphenyl)-diphenyl methane; and 1,1-bis(4-hydroxyphenyl) fluorenone; and
- (b) from about 99 to about 1 weight percent of a copolymer containing in mole percent from about 75 to about 87 recurring units of a monovinyl aromatic monomer and from about 13 to about 25 recurring units of an N-arylmaleimide monomer, wherein the polyarylate and the copolymer are fully compatible upon blending and the resulting polymer composition exhibits a single phase and a single glass transition temperature value.
- 2. The composition of claim 1 in which the monovinyl aromatic monomer of copolymer (b) is selected from the group consisting of styrene, p-methylstyrene, and t-butylstyrene.
- 3. The composition of claim 1 in which the N-arylmaleimide monomer of copolymer (b) is selected from the group consisting of N-phenylmaleimide, N-(4-t-butyl)phenylmaleimide, N-(2-chloro)phenylmaleimide, and N-(4-methoxy)phenylmaleimide.
