Process for producing and polyester compositions comprising lactamyl phosphites as chain extending agents |
摘要 |
Processes for producing and polyester compositions of intermediate and high molecular weights are attained by reacting with at least one lower molecular weight polyester with an effective amount of a lactamyl phosphite as a constituent. The reaction may be carried out by blending these constituents and any other optional constituents and is preferably formed by melt blending.
