Reactive Extrusion of Polyolefins and Their Blends

Korea Polymer Journal, Vol.4, No.2, 215-226, October, 1996

Reactive extrusions of high density polyethylene(PE), isotactic polypropylene (PP), PE/PP, and PP/EPR(ethylene-propylene rubber) blends were carried out in the presence of poly-functional monomers(coagent) as well as peroxide. Effects of type and concentration of coagent were extensively studied in terms of rheology, morphology, thermal and mechanical properties. The acrylate type coagents gave most significant effects on the crosslinkings of PP.Peroxide and coagent added during extrusion remained effective during injection, leading to a significant change in flow properties upon injection. Crosslinking and chain scission were very sensitive to the viscosity ratio, as well as to the composition in PE/PP blends.
