✦ Synopsis
Tracer techniques have been used in the determination of monomer reactivity ratios for the radical binary copolymerizations of various esters of methacrylic acid; most of the reactions were performed at 60 °. The results are used for comparison of the reactivities of the monomers towards polymer radicals. There is evidence that depropagation may become significant at 110 ° for the polymerization of phenyl methacrylate.
