Claim Text:
1. A process for making a comb polyolefin, comprising: a) reacting a multifunctional acrylate monomer with a α,ω-diene monomer to form an alternating acrylate/diene copolymer and b) reacting the alternating acrylate/diene copolymer with a vinyl-terminated polyolefin, wherein the α,ω-diene monomer has the general formula CH2=CH—CH2-X—CH2-CH═CH2, wherein X is a linear molecular structure with an atom number of 4 to 100, wherein the linear molecular structure is an alkyl group or ethylene oxide, wherein the multifunctional acrylate monomer is selected from the group consisting of pentaerythritol tetraacrylate, trimethylolpropane triacrylate, trimethylolpropane ethoxylate triacrylate, glycerol propoxylate (1PO/OH) triacrylate, 1,3,5-triacryloylhexahydro-1,3,5-triazine, tris[2-(acryloyloxy)ethyl]isocyanurate, di(trimethylolpropane) tetraacrylate, and dipentaerythritol hexaacrylate, wherein the multifunctional acrylate monomer is in slight molar excess compared to the α,ω-diene monomer, and wherein the olefins of the polyolefin of the vinyl-terminated polyolefin have from 2 to 8 carbons per monomeric unit.
