ABSTRACT:
Disclosed are thermoplastic blends of polyesteramides and poly(phenylene ether) resins as well as methods for preparing said polyesteramides and polycarbonate blends thereof. Preferred polyesteramides are those comprising amide units of formula (I) ##STR1## and ester units of formula (II) ##STR2## wherein the ratio of (I) to (II) is at least 1:1, and more preferably wherein at least 80% of the units of formula (I) are separated by at least one of the units of formula (II). The thermoplastic blends may additionally contain compatibilizers for the polyesteramide and poly(phenylene ether) resins.
