摘要

Copolu00ecmero, process to prepare a copolu00ecmero in multiblocos, copolu00ecmero in multiblocos, functionalised derivative, polymer blends, homogeneous, and polu00ecmero.Copolymers, especially in multiblocos copolymer containing two or more segments or blocks, are prepared polimerizando propylene, 4 - methyl - 1 - pentene, or other 244 - olefin of C ~ 4 - 8 ~ in the presence of a composition comprising a mixture or reaction product resulting from comb Inar: (a) a first catalyst for polymerization of olefin.(E) a second catalyst for polymerization of olefin capable of preparing a polymer having increased incidence of branching regio - irregular compared with that of the polymer prepared by catalyst (a) under equivalent conditions of polymerization, and (c) an agent to exchange chain.
