ABSTRACT:
Disclosed are blends of low-melting, slowly crystallizing copolyesters or of substantially amorphous copolyesters having relatively high glass transition temperatures containing very small amounts of low-molecular-weight polyolefins. These blends have sharply increased crystallinity and crystallization rates and provide significant improvements in production because of the enhanced crystallization.
