    Abstract: A thermoplastic resin composition comprises units represented by the amide formula (I): ##STR1## and the ester formula (II): ##STR2## wherein said amide units are present as a physical mixture in said resin or as a polymer with the repeating ester units to impart an enhanced crystallization rate as compared to said resin without said amide units of formula (I), said amide units being present in an effective amount to decrease the difference between the temperature of melting and the temperature of crystallization of said resin to an amount less than 5 mole percent of amide unites of formula (I) based on the moles of ester units of formula (II).

    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.
