The morphology of ethylene-vinyl chloride copolymers containing up to 8 wt yo vinyl chloride obtained in various copolymerization coiiditions is studied. Fundamental morphological units of the copolymers were determined, arid one of the most probable mechanisms responsible for their aggregatiori in
It is demonstrated that the catalyst system bis(pentamethylcyclopentadienyl)-zirconium dichloride (Me 5 Cp) 2 ZrCl 2 -methylaluminoxane (MAO) is able to produce random copolymers of ethene and 1-hexene. The 1-hexene incorporation in the copolymers is extremely small. Even in the case of a molar rati
