Polymerization with Presence of Polymers

IV. Graft-polymerization of Acrylonitrile on to Polyvinyl Acetate and Its Spinning Experiments

Abstract

Acrylonitrile is polymerized in emulsion or solution with presence of polyvinyl acetate and graft polymers are found to form between two polymers. The grafted polymers are spun into fibers from dimethyl formamide solution. The fiber obtained from grafted polymers is more heat-resistant than that of copolymer or mixture. These results are coincided with that previously reported by Mori and Sakurada (on polyvinylalcohol fibers) and also by Coleman (on polyethylene terephthalate fibers).
