Graft Copolymerization of Methyl Methacrylate onto Poly(ethylene-co-propylene)

The graft copolymerization of methyl methacrylate (MMA) onto amorphous ethylene-propylene copolymer (EPC) with benzoyl peroxide (BPO) as the initiator was studied. The influence of reaction parameters, such as MMA, EPC, BPO concentrations and temperature, on the extent of grafting were described and discussed. Solvent extraction, infrared spectra (IR), H NMR, and turbidimetric titration verified the existence of a grafted copolymer. The grafted copolymers were also characterised by their rheology behaviour in xylene solutions.
