ABSTRACT:
This invention relates to a process of modifying the crystallization temperature (T.sub.cc) of polymers, such as polyesters or polyamides, the polymers produced by this process and the molding compositions containing these polymers. The process comprises cooling a polymer to a temperature sufficient to allow grinding of the polymer to an effective particle and then grinding said polymer to the effective particle size in order that the polymer exhibits an increased T.sub.cc.
