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.
