Vinyl-Cellulose Copolymers

Abstract

Graft copolymerization reactions of methyl, ethyl, butyl, hexyl, and lauryl methacrylates and 1,3-butylene dimethacrylate with fibrous cotton cellulose were initiated by the simul taneous irradiation procedure, using ⁶⁰Co γ-radiation. The fabric properties of the poly(alkyl methacrylate)—cotton copolymers (methyl, ethyl, butyl, and hexyl) were determined at two degrees of grafting. The flex abrasion resistance of the poly(hexyl methacrylate)—cotton copolymer at 37% add-on of polymer was more than ten-fold that of the cotton fabric control. The flat abrasion resistance of the poly(ethyl methacrylate) —cotton copolymer was ten-fold greater than that of the fabric control. Examination of electron microphotographs of thin sections of the copolymers embedded in aqueous polyvinyl alcohol indicated that layer opening of the fibrous structure occurred during graft copolymerization and that the degree of layering and size of the opening was related to the molecular weight of the monomer being reacted. The radiochemical yields of the reactions ranged from 4,600 to 44,000 molecular actions per 100 eV at a dosage of 0.5 MR.
