| Abstract: | PE-poly(hexene-1) compositions were synthesized via successive polymerization of the corresponding monomers in the presence of a titanium-magnesium catalyst. It was shown that a PE-poly(1-hexene) diblock copolymer is formed along with homopolymers of ethylene and 1-hexene during the polymerization. Nascent samples of these polymer blends are characterized by exceptionally high melting temperatures and heats of melting of the PE component (up to 149°C and 278 J/g, respectively). |
