Experiments on radioinduced graft copolymerization of binary mixtures such as butadiene -- styrene, butadiene-acrylonitrile, styrene-- acrylonitrile and some other systems onto cellulose and PVA (polyvinyl alcohol) fibers were carried out with the use of methanol as a solvent. A very marked maximum of graft was observed in every case at a certain composition of the comonomer mixture. It seemed that such a marked maximum was closely connected with popcorn polymerization for the case of butadiene-- styrene, but popcorn polymerization was not a necessary condition for the appearance of the maximum. Only a combined effect of swelling of the gel, formation of radicals in the gel, homocopolymerization, and some other unknown factors is considered likely to lead to a very high degree of grafting.
