  • Improvement of Impact Strength of PP/EPDM Blends by Novel Dynamic Crosslinking.

説明

Novel dynamic crosslinking reaction with the N, N″-m-phenylene-bis-maleimide/dihydroquinoline derivative system was carried out on various PP/EPDM blends, and its effect on Izod impact strength (IIS) was investigated. The system crosslinked EPDM domains selectively and did not degrade PP matrices virtually. The IIS increased on crosslinking. During the reaction, PP/EPDM graft-copolymers were produced at the PP-EPDM interfaces to strengthen the interfacial adhesion. The resultant high interfacial adhesion sustained de-bonding at the interfaces under stress and permitted to develop stress concentration zones into PP matrices effectively. When the developed concentration zones were close enough to interact, shear yielding increased the IIS's dramatically. The dynamic crosslinking thus caused a dramatic increase of the IIS's of PP/EPDM blends not only at a low EPDM wt% but also at a low temperature. The crosslinked EPDM domains acted as nucleating agents and affected the characters of the crystalline structure and tie molecules. These effects may also increase the IIS.
