Abstract

The effects of some factors, i.e., long chain branches on EPDM and PP backbone and short side chain branches of HDPE on MELT EXTENSIBILITY and melt elasticity were studied and compared with those of TERNARY BLENDS of linear PPs. Long chain branched EPDM, long chain BRANCHED PP, and linear PE with small side chains were used to increase the molecular entanglements and melt drawability and to improve melt elasticity. Using three linear PP in the blends, showed a synergistic effect on melt elasticity in a certain percentage of composition. The experimental results have been indicated that both TERNARY BLENDS of linear PPs and TERNARY BLENDS containing a BRANCHED PP increased molecular entanglements and affected on melt elasticity. HDPE as a polyolefin with short side chains showed better effect on melt elasticity and melt drawability than ternary linear PP blends. Long chain branches of EPDM considerably improved its damping factor (tan d) and steady state creep compliance (Je0). The effect of long chain branched EPDM and high molecular weight linear PE with small branches, on melt tension force and damping factor of blends were measured and compared with those of blends containing a long chain BRANCHED PP. Long chain BRANCHED PP(LCB-PP) showed a distinct effect on MELT EXTENSIBILITY of blends. The most significant effect is observed by using the PE and long chain BRANCHED PP, both.
