Abstract

The chain-extending efficiency of epoxy-type chain-extender to PA66 was investigated by an in-situ melting chain-extending method. The results show that the viscosity of the chain-extended PA66 increases, and its mechanical properties ob viously increase as well. Crystalline behavior studies show that the crystalliza tion inducement t1 and the crystallization half-time t1/2 of the extended PA66 reduce. It indicates that EP also acts as a nucleating agent.
