METHOD FOR PRODUCTION OF CATALYST, CATALYTIC SYSTEM FOR POLYMERIZATION OF OLEFINS, METHOD FOR POLYMERIZATION OF OLEFINS Russian patent published in 1998 - IPC

Abstract RU 2118329 C1

FIELD: polymerization of olefins, production of polymer controlled structural characteristics. SUBSTANCE: catalyst is prepared by interaction of dialkyl magnesium of alkyl magnesium halide with silicium halide or with tin halide. The process is carried out in inert organic solvent solution. Then thus prepared granulated solid precipitate is suspended, the process takes place in inert organic solvent, it is followed by interaction with compound having formula I wherein M is metal of VIB group of Periodical Table. R and Cp are given in specification. Then granulated solid catalyst is isolated of thus prepared suspension. Method for polymerization of olefins in which proposed catalytic system used is also proposed here. EFFECT: improved efficiency of the method; improved quality of product. 15 cl
