Ethylene/Propylene/Diene Terpolymers Grafted with Poly(methyl acrylate) by Reverse Atom Transfer Radical Polymerization

This article describes the synthesis of ethylene-propylene-diene terpolymers grafted with poly(methyl acrylate) (PMA) by reverse atom transfer radical polymerization. The PMA graft molecular weights and densities are controlled by varying the concentration and conversion of methyl acrylate, as well as the concentration of initiator. The grafted copolymers are characterized by Fourier-transform infrared spectroscopy, proton NMR, and gel permeation chromatography. Copolymers with graft molecular weights varying from 12 to 179 kDa and grafting densities from 11% to 53% are made following this procedure.
