Abstract
A thermoplastic molding composition comprising an aromatic carbonate polymer and a polyester derived from a cyclohexanedimethanol.
Claims22
A transparent polymer blend essentially free of halogenated aromatic polycarbonate and not containing glass fibers comprising:
- (a) a nonhalogenated aromatic carbonate polymer and
- (b) between 10 and 99 parts by weight of a polyester polymer derived from:
- (1) glycols of the group consisting of cyclohexanedimethanol and cyclohexanedimethanol with a minor amount of a bifunctional glycol selected from the group consisting of ethylene glycol, propylene glycol, butylene glycol, pentylene glycol, hexylene glycol, heptylene glycol, octylene glycol, nonylene glycol and decylene glycol, and
- (2) a dicarboxylic acid of the group consisting of terephthalic acid and a mixture of isophthalic and terephthalic acids.
