Abstract: A process for making a hyperbranched polyethylene. The process has the steps of (a) reacting a multifunctional acrylate monomer with an α,ω-diene monomer in the presence of a first catalyst to form an alternating acrylate/diene copolymer and (b) reacting the alternating acrylate/diene copolymer with a late transition metal α-diimine catalyst to form a multi-nuclear initiator for chain walking polymerization of ethylene. There is also a process for forming a multi-nuclear initiator. There is also a hyperbranched polymer.

Abstract: Provided is an alternating block copolymer. The alternating block copolymer has an olefin polymer block and an poly(alkyl methacrylate) block. The olefin polymer block has monomeric units of one or more alpha olefins of 2 to 12 carbon atoms that make up 90 wt % or more of the total weight of the olefin polymer block. The olefin polymer block exhibits a number average molecular weight of the olefin polymer block is 1000 to 500,000. The poly(alkyl methacrylate) block has monomeric units of one or more alkyl methacrylates with alkyl side chains of 1 to 100 carbon atoms that make up 90 wt % or more of the total weight of the poly(alkyl methacrylate) block. The poly(alkyl methacrylate) block exhibits a number average molecular weight of 1000 to 500,000. There is also provided a lubricant composition containing the alternating block copolymer and a process for making the alternating block copolymer.
