ABSTRACT:
Disclosed are blends of polyesteramides and polyester resins, optionally with polycarbonates, as well as methods for preparing said 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).
