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).
