Melt State Branching of Polypropylene/Polybutene-1

In this survey Polypropylene and its blend with 10 and 20 Wt% Polybutene-1 were branched through reactive extrusion process in the presence of three methylol propane three methacrylate (TMPTMA) multifunctional monomer (1, 1.5, 2, 3 Wt%), 0.03, 0.05, 0.07, 0.1 Wt% Dicumyle peroxide (DCP)) and 600 PPM Irganox1010 antioxidant. The long chain branched structure affect the strain hardening behavior in elongational mode of deformation. The formation of branched structure is approved by shear and extensional rheometry. The results indicated that polybutene-1 is more potent than PP in the branching process
