THERMAL STRESS BEHAVIOR OF RADIATION-INDUCED GRAFT POLYMERS OF COTTON
Second-order transition temperatures of selected radioinduced graft polymers of fibrous cotton cellulose are presented, and the thermal stress behavior of the products is discussed. Graft polymers of cotton in the form of yarns were thermoplastic, probably due to lowered cohesive forces of the cellulose. Graft polymers of cottonpolystyrene showed a drop in resiliency index and stiffness with increasing temperature at about 100 deg C, while graft polymers of cotton-polyacrylonitrile and cyanoethylated cotton-polyacrylonitrile showed drops in resiliency index and stiffness at 80--100 deg C. On relaxation, the recovery of the energy expanded to elongate graft polymers of cotton to about 1.5% was about 40%, except for cyanoethylated cotton-polyacrylonitrile, where about 66% recovery was observed.
