โœฆ Synopsis


Homopolymerizations and copolymerizations of methyl methacrylate (MMA) and methyl acrylate (MA) have been performed in the presence of either stilbene or p.fluorostilbene, labelled with carbon-14, it has been shown that at 60ยฐC the polyMA radical is much more reactive than the polyMMA radical towards stilbene, the velocity constants for the reactions differing by a factor of about 300; similar results are found for p.fluorostilbene. The differences between the reactivities of the radicals are associated with steric effects arising from the presence of a methyl group at the alpha position in ~tMA.

## Graft copolymers of methyl acrylate, ethyl acrylate and ethyl methacrylate on carboxy methyl cellulose (d.S 040.5) were obtained by the use of ceric ion in aqueous media at 35ยฐC. The extent of graft polymer formation was measured in terms of graft level, molecular weight of the grafted polymer
