Vinyl acetate)-(methyl methacrylate) copolymers have been prepared by solution polymerization in benzene at 60 Β° using benzoyl peroxide as initiator. Compositions of the copolymers have been determined using IH-NMR spectroscopy. Reactivity ratios are rv =0.04, ru = 32.2 (Fineman-Ross); r v = 0.036 \
