    Abstract: The present invention relates to a composition comprising: a heterophasic polypropylene containing i) a matrix phase of a propylene homopolymer and/or a propylene copolymer with up to 3 wt. % of ethylene and/or at least one C4-C8 α-olefin, the wt. % based on the weight of the copolymer and ii) a disperse phase of an ethylene-C3-C8 α-olefin copolymer, wherein the ethylene content is at least 40 wt. % based on the weight of the ethylene-C3-C8 α-olefin copolymer, one or more of a compatibilizer, wherein the compatibilizer is i) a non-aromatic polyester having an average M/E ratio of at least 10 and/or ii) a block copolymer comprising a polypropylene block and a polyester block, said polyester being a non-aromatic polyester and having an average M/E ratio of at least 10, wherein M is the number of backbone carbon atoms in the polyester, not including the carbonyl carbons and E is the number of ester groups in the polyester.

    IPC: C08G81/02

    Abstract: The present invention relates to a process for the preparation of a block copolymer comprising a first type of polyolefin block and at least one type of second polymer block, the process comprising the steps of: A) polymerizing at least one type of olefin monomer using a catalyst system to obtain a first polyolefin block containing a main group metal on at least one chain end; the catalyst system comprising: i) a metal catalyst or metal catalyst precursor comprising a metal from Group 3-10 of the IUPAC Periodic Table of elements; and ii) at least one type of chain transfer agent; and iii) optionally a co-catalyst; B) reacting the first polyolefin block containing a main group metal on at least one chain end obtained in step A) with at least one type of oxidizing agent and subsequently at least one type of metal substituting agent to obtain a first polyolefin block containing at least one functionalized chain end; C) forming at least one second polymer block on the first polyolefin block, wherein as an initiator the functionalized chain end of the first polyolefin block obtained in step B) is used to obtain the block copolymer.
