Diffusion and Copolymerization of Polyacrylic Acid in Nylon 66 Fibers to Achieve Improved Thermal Protection and Higher Moisture Regain
Abstract
Grafting of polyacrylic acid monomer to nylon 66 textile material was investigated to increasemoisture absorption and melting temperature of nylon 66. The copolymerization or fixation of a relatively low molecular weight polyacrylic acid to nylon 66 by a heat cure reaction is described. Diffusion and copolymerization of polyacrylic acid in nylon 66 fibers has been attained as indicated by examination of stained fiber cross-sections and isolation of reacted material. The mechanisms of the reaction appears to involve the amine end groups of the nylon 66 by formation of a block copolymer.
