COMPOUNDS, CATALYTIC COMPOSITION, METHODS FOR HOMO- AN CO-POLYMERIZATION Russian patent published in 2008 - IPC C07F7/00 C07F7/22 C08F10/10 

Abstract RU 2316559 C9

FIELD: chemistry of metalloorganic compounds, catalysts.

SUBSTANCE: invention relates to a metalloorganic compound and catalytic composition comprising indicated metalloorganic compound of the general formula (I): [HC(CRR'R'')(CRR'R'')]+[M2X9]- wherein R means hydrogen atom (H) or M1R1R2R3; R' means M1R4R5R6; R'' means H, (C1-C12)-alkyl; M means Zr or Hf; M' means Si or Sn; X means halogen atom; R1-R6 mean (C1-C12)-alkyl. Also, invention relates to a method for homo- and co-polymerization of isoolefins or olefins in the presence of indicated metalloorganic compound. Described catalytic system based on compound of the formula (I) shows high activity in the co-polymerization reaction of isobutylene.

EFFECT: valuable chemical and catalytic properties of compound.
