Propylene copolymerization with 1-hexene and 4-methyl-1-pentene in liquid propylene medium in presence of MAO-activated C-2-symmetry ansa-zirconocene rac-Me2Si(4-Ph-2-MeInd)(2)ZrCl2 was studied. Random copolymers of propylene with 1-hexene and 4-methyl-1-pentene content up to 7 mol% were obtained at 60 degrees C. General kinetic characteristics of propylene/higher alpha-olefin copolymerization were evaluated. The distinct feature of propylene copolymerization with 1-hexene and 4-methyl-1-pentene in liquid propylene medium - the proximity of comonomer relative reactivity ratios (tau(2)-tau(1)-1) that indicates azeotropic nature of copolymerization processes in studied conditions. Synthesized copolymers were characterized with the use of IR, C-13 NMR, GPC, WAXD, DSC techniques, and uniaxial tensile testing.
