MANUFACTURE OF NEW GRAFT COPOLYMERS

Patent ·
OSTI ID:4010249

A process for the production of graft copolyers of cellulose triacetate and styrene is described. Cellulose triacetate is subjected to ionizing radiation in the presence of oxygen to form peroxidized active centers (defined in report) on the cellulose triacetate, and the irradiated material is then contacted with monomeric styrene. Instead of styrene, a nuclear-methyl derivative of styrene may be used (a methyl substitution product in which the methyl group or groups are in the nucleus), for example, vinyl toluene or vinyl xylene. Ortho-, meta-, or para-, vinyl toluene, or a mixture of two or all, may be used as isomers. The irradiated material is advantageously contacted with the styrene in the absence of oxygen, in a vacuum or under nitrogen. (N.W.R.)
