CATALYSIS FOR POLYMERIZATION OF ALPHA-OLEFINS, METHOD OF HOMO-AND COPOLYMERIZATION OF ALPHA-OLEFINS AND METHOD OF PREPARING ELASTOMERIC ETHYLENE COPOLYMERS Russian patent published in 2001 - IPC

Abstract RU 2172746 C2

FIELD: chemistry of polymers. SUBSTANCE: described is catalyst for polymerization of alpha-olefins, comprising compound of general formula I: wherein X is selected from halogen, n is integer of 2 to 18; R and R* are selected from H, alkyl radicals having from 1 to 5 carbon atoms; M is zirconium provided that in general formula II number of radicals R other than H does not-exceed 2, at least one of two radicals R* is H except for compound which has n=4, R=R*=R=H.. Also described are method of homo- and copolymerization of alpha-olefins and method of preparing elastomeric copolymers. EFFECT: copolymers with viscosity suitable for use. 25 cl, 4 tbl
