CATALYST AND ALPHA-OLEFIN POLYMERIZATION PROCESS

摘要

FIELD: polymerization catalysts. SUBSTANCE: catalyst contains (a) bis(cyclopentadienyl-bis-amide) derivative of IVB group metal: (I) where M is metal, R1, R2, R3 and R is C1-4-alkyl, and Cp is defined in description; and (b) aluminoxane cocatalyst. EFFECT: increased catalytic activity in polymerization and copolymerization of ethylene and alpha-olefins. 6 cl, 6 exu
