Studies in Chain Transfer. Part VII. Polymerisation of Methyl Acrylate and Styrene

methyl actylate has been polymerised in bulk using hydrogen peroxide as initiator at 50°, 60°, and 80°. The kinetic constants \(\delta\), CM and. C1 have been evaluated and Rp is Found to be proportional tc 10.5. From the thermal polymerisation of methyl acrylate in solution, ohain transfer values for eighteen solvents he we been determined. values for some solvents in the polymerisation of methyl methacrylate and styrene, hitherto oat reported, have also been evaluated. The trend of the values with the nature of the solvent-monomer pair and radical reactivity has been discussed in detail
