Abstract

Abstract: The interfacial structure and interaction of ternary blends of HDPE, carboxylated polyethylene(PE-MA)and CaCO₃ grafted with acrylamide(CaCO₃-AA)have been studied. It was found that the improvement of interfacial adhesion by the PE-MAand CaCO₃-AAis clearly revealed in the SEMof the fracture surface, which leads not only to the increase of the tensile strength, but also to the increase of the toughness.This behavior has been attributed to a series of chemical and physico-chemical interactions taking place between the two components during the blending process which were conformed by FTIR, DSCand extraction experiments.

Key words: Inorganic filler, HDPE, Interfacial modification, Toughening and reinforcement improvement
