Notes:
Copolymers of ethylene with propylene, butene-1 and hexene-1 were prepared using a titanium-magnesium (TMC) or a vanadium-magnesium catalyst (VMC). The copolymers were examined for thermal stability by TGA, melting and crystallization behaviour by DSC and crystallinity by XRD. Fractionated samples of ethylene-hexene-1 copolymers were also similarly characterized. Results indicate that VMC produces copolymers with a higher degree of crystallinity and greater compositional homogeneity than TMC.
