Abstract

Because of the interdependency between molecular structure, RHEOLOGICAL PROPERTIES and material response during processing, the RHEOLOGICAL PROPERTIES of CONTROLLED-RHEOLOGY POLYPROPYLENE (CR-PP) are investigated. The reactive experiment is carried out in a modular self-wiping co-rotating twin-screw extruder. The initiator was dicumylperoxide (DCP). The concentration range of DCP was 0.02-0.6% by wt. The purpose of this study was to characterize the influence of PEROXIDE DEGRADATION on RHEOLOGICAL PROPERTIES of POLYPROPYLENE homopolymer. The results showed that RHEOLOGICAL PROPERTIES of PP change with PEROXIDE DEGRADATION significantly. With increasing of peroxide concentration the complex viscosity ( h*) and torque decrease. Degraded resins had more Newtonian behaviour than original resins. Storage modulus (G’) and loss modulus (G”) decreased with peroxide concentration. Dissipation factor (tan d) and complex compliance (J*) increased with increasing DCP concentration.
