Process for the polymerization of olefins |
| abstract |
A multistep process comprising the following steps:n step a) polymerizing propylene and optionally one or more monomers selected from ethylene or alpha olefins of formula CH 2 ═CHT 1 wherein T 1 is a C 2 -C 10 alkyl radical in the presence of a catalyst system supported on an inert carrier, comprising:n ii) one or more metallocene compounds of formula (I): n nn n n n n n n n n n n n n n ii) an alumoxane or a compound capable of forming an alkyl metallocene cation; and optionally n iii) an organo aluminum compound; n n n step b) contacting, under polymerization conditions, in a gas phase, propylene or ethylene with one or more alpha olefins of formula CH 2 ═CHT, wherein T is hydrogen or a C 1 -C 10 alkyl radical, and optionally a non-conjugated diene, in the presence of the polymer obtained in step a) and optionally in the presence of an additional organo aluminum compound; provided that an homopolymer is not produced; n wherein: the compound of formula (I) is described in the application. |
