摘要

"Metalocenos heterocu00ecclicos, binders, catalu00ectico system and process for the polymerization of monu00c8meros polymerisable by addition".There are described a new class of heterocyclic metalocenos,A catalytic system containing these and process for the polymerization of polymerisable monomers in addition; the heterocyclic metalocenos correspond to formula (I): y ~ J ~ R ~ I ~ Z ~ JJ ~ ~ K ~ p ~ I mEq~ (I) in which: y is a group containing a radical coordenante central six electrons 227 directly coordinating me,Which are fused to one or more rings containing at least one atom is different from carbon chosen from among B, N, O, Al, P, s, GA, Ge, in, Sn,,,Sb and T; R "is a bridge divalente between groups y and Z; Z is a group coordenante optionally having the same meaning of Y; m is a transition metal; q is halogen or substituent hidrocarboneTOS; P is a counter ion; R is 0 or 1; J is 1 to 3; JJ is 0 to 2; K is 1 - 3; L is 0 - 2.
