Abstract
This invention relates to thermoplastic molding compositions comprising the following: PA1 (a) about 5 to about 95% by weight of a polyester or a polyester, comprising: repeat units derived from terephthalic acid, ethylene glycol, and 1,4-cyclohexanedimethanol wherein the mole ratio of ethylene glycol to 1,4-cyclohexanedimethanol is from 66:34 to 98:2, said polyester having an I.V. of about 0.3 dL/g to about 1.2 dL/g, and PA1 (b) about 5 to about 95% by weight of a polyphenylene ether. The compositions are useful for producing clear articles by injection molding or extrusion.
