  • Patent number: 10533075
    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 initiat

  • Patent number: 10472447
    Abstract: The present invention relates to a process for the preparation of a graft copolymer comprising a polyolefin main chain and one or multiple polymer side chains, the process comprising the steps of: copolymerizing at least one first type of olefin monomer and at least one second type of metal-pacified functionalized olefin monomer to obtain a polyolefin main chain having one or multiple metal-pacified functionalized short chain branches, and reacting the polyolefin main chain having one or multiple metal-pacified functionalized short chain branches with at least one metal substituting agent to obtain a polyolefin main chain having one or multiple functionalized short chain branches; and forming one or multiple polymer side chains on the polyolefin main chain, wherein as initiators the functionalized short chain branches on the polyolefin main chain are used to obtain the graft copolymer. The invention also relates to the products obtained therefrom.
