PROCESS FOR PRODUCING POLYESTER OR POLYAMIDE COMPOSITIONS COMPRISING LACTAMYL PHOSPHITES AS CHAIN EXTENDING AGENTS

摘要

Polyester or polyamide compositions of intermediate and high molecular weights which are attained by reacting at least one lower molecular weight polyester or polyamide with an effective amount of a lactamyl phosphite. The reaction may be carried out by blending these constituents and any other optional constituents and is preferably formed by melt blending.
