... THE EFFECT OF CATALYST ON INTERMOLECULAR HETEROGENEITY DISTRIBUTION IN ETHYLENE/1-HEXENE COPOLYMERS . ... Copolymers of ethylene with higher 1-olefins are important class of polymer products due to their specific properties. Ethylene/a-olefin copolymers properties depends not only on the type and amount of the a -olefin comonomer in the polymer but also on its distribution along the polymer chain [1]. ...
