IMPROVEMENT OF THERMAL STABILITY OF TEXTILE FIBERS
Abstract
Copolymerization of vinyl acetate with acrylonitrile proceeded well, and substantial amounts of vinyl acetate were introduced without damaging the meltproofing quality. The way is now open to combine or graft various flameproofing materials onto the hydroxyl groups resulting from vinyl acetate hydrolysis. The continuation of our nitrosation work has brought progress along 2 lines. Although the nitroso group itself does not seem to work too well as a free radical source, the reduction to the amine group proceeded smoothly, and another grafting spot was made onto the nylon for the anchorage of flame retarding agents. In the course of the work to attach P compounds in this manner, very interesting reactions were observed between halogen phosphorous and nylon. These P compounds appear to impart appreciable flame stabilization and have substantial crosslinking action with respect to the nylon. It appears possible to use a melt retarding agent which at the same time would be flame retarding. (Author)
