摘要

正

Three polycaprolactam samples modified by 0.05—0.50% polybenzimidazole （PBI） by weight were prepared. Their structure and mechanical properties were characterized by means of FT-IR

DTA

impact and viscoelastic method. PBI delayed the superimposed polymerization-crystallization process of the activated anionic polymerization of caprolactam. The monomer casting （MC） nylons modified by PBI had lower crystallinities

lower T

and more nearly perfect spherulites than MC nylon itself

and showed a typical toughening effect.
