COMPOSITION OF INTERPOLYMER IN ETHYLENE / α-OLEFIN BLOCKS, INTERPOLYMER IN PROPYLENE / α-OLEFIN BLOCKS, ARTICLE AND PROCESS FOR POLYMERIZATION OF ONE OR MORE POLYMERIZABLE MONOMERS BY ADDITION

摘要

Interpolymer composition in blocks of ethylene /alpha -olefin, interpolymer in blocks of propylene /alpha -olefin, article and process for polymerisation of one or more polymerizable monomers by addition additions of the invention provide a class of interpolymers in propyl blocks In /alpha -olefin separated by mesophase with controlled block sequences. Propylene /alpha -olefin interpolitors are characterised by a deblocum mean index, ABI, which is greater than zero and up to about 1 and a molecular weight distribution, MW /mn, greater than about 1,4. The block index is preferably about 0,2 to about 1. In addition or alternatively,The interpolymer in propylene /a -olefin blocks is characterised by at least a fraction obtained by fractional elution with a temperature gradient ("tref"),Which has a block index larger than about 0,3 and up to about 1,0 and the propylene /alpha -olefin interpomer has a molecular weight distribution, MW /mn, greater than about 1,4.
