PROCESS FOR PREPARATION OF MODIFIED POLY(TRIMETHYLENE TEREPHTHALATE)

摘要

An improved process is provided for making a shaped article of a modified poly(trimethylene terephthalate) polymer wherein the intrinsic viscosity of the modified poly(trimethylene terephthalate) present in the shaped article is at least 95% that of the intrinsic viscosity of the poly(trimethylene terephthalate) prior to modification.
