Method for producing a heterogeneous polymer blend

摘要

In the method for producing heterogeneous polymer blend, in the presence of a supported catalyst, by polymerizing in a first reaction zone, the degree of crystallinity to prepare the first polymer of at least 30% of the first at least one monomer. Is contacted with a sufficient environment and polyene one degree of crystallinity to prepare the second polymer is less than 20% and at least a second at least one monomer, at least a portion of said first polymer. One fraction is insoluble in xylene at least a second polymer, and to have a phase second polymer wherein the first polymer is different from the second polymer is at least partially crosslinked in the second polymerization zone that.
