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.
