摘要

Composition for use in preparation of copolu00ecmeros in multibloco, process to prepare a copolu00ecmero in multibloco, copolu00ecmero in multibloco and derivative cross-linked a copolu00ecmero in multibloco.The present invention includes a composition for use in forming a multibloco copolymer, said copolymer containing two or more segmetos or blocks that differ with respect to the physical or chemical properties, polymerization process using the same, and the polymers obtained Tes.And the composition comprises a mixture or reaction product resulting from the combination of: (a) a first catalyst for polymerization of olefin metal complex.(b) a second catalyst for polymerization of olefin metal complex capable of preparing polymers that differ with respect to the chemical or physical properties of the polymer prepared by the catalyst (a) under conditions of polymerization equivalent, and (c) an agent of transport D. And the chain.
