Structure-property relationships in poly-(propylene-ethylene) copolymers
… and the mechanical properties of poly-(propylene-ethylene) bi-phasic copolymers. The copolymers investigated covered a comonomer content ranging between 4 and 23 percent ethylene. Nine grades were considered, with variables such as the melt flow index, the degree of crystallinity, the …

An investigation into the impact fracture behaviour of poly (propylene-ethylene) copolymers using an instrumented low temperature drop weight impact tester
… weight impact behaviour and fracture of poly (propylene - ethylene) copolymers at cryogenic temperatures. A cryogenic temperature facility was incorporated into the existing instrumented drop weight impact tester to allow for variation of the impact test temperatures.

Morphology, Crystallization and Melting Behavior of Propylene-Ethylene Statistical Copolymers
… and melting behavior of novel Dow Chemical propylene-ethylene copolymers were investigated. The incorporation of ethylene units into a polypropylene chain resulted in the decrease in crystallization, melting and glass transition temperatures and overall crystallinity. Based on the shape of …
