Abstract

PURPOSE:To readily and efficiently obtain an acrylate or methacrylate graft copolymer of an olefin copolymer, by using a specific organic peroxide based catalyst in polymerizing an acrylate or methacrylate in the presence of an olefin.copolymer. CONSTITUTION:An acrylate or methacrylate is polymerized in the presence of an olefin.copolymer (preferably ethylene.propylene copolymer, etc.) using an organic peroxide based polymerization catalyst (preferably di-tert-butyl- diperoxyphthalate, etc.) capable of forming two or more radicals in 1mol. of the catalyst after decomposition, preferably at 90-140 deg.C. Furthermore, the olefin.copolymer is preferably used in a state of a solution thereof dissolved in mineral oil, etc., to reduced viscosity in polymerizing the (meth)acrylate.
