A novel method of preparing some new αα‐disubstituted vinyl monomers and their polymerizability. I. Synthesis of methyl α‐phenoxymethylacrylate and its polymerizability

By exposure to ultraviolet and gamma radiation and by the usual methods of thermal polymerization, the stereospecific polymerization of methyl aryloxymethacrylates was carried out at different temperatures in several solvents. Triad tacticity values of the polymers obtained by free‐radical and ionic routes were computed from nuclear magnetic resonance spectral data. Results of this investigation support our earlier observation that, under the conditions used, heterotactic content is the maximum in most of these polymers, thereby justifying the high steric effect of the bulky and polar aryloxy side chain which offers equal isotactic and syndiotactic placements.

synopsisHigh polydispersity values obtained for the molecular weights, as determined by light scattering, omnometry, and GPC, of polymers prepared by different methods from the monomers recently synthesised indicate the presence of large quantities of low molecular weight species besides the high molecular weight species. Intrinsic viscosity data were used to evaluate Mark-Houwink constants K and "a" for this new series of monomers. DSC analyses show that the polymers have low Tg. X-ray *action studies made on the fibers show a high percentage of crystallinity in poly(methy1 a-phenoxymethacrylate).
