Molecular weights of grafted polystyrene onto γ‐preirradiated cellulose diacetate

摘要

AbstractThe behavior of molecular weights of grafted polystyrene onto γ‐preirradiated cellulose diacetate was studied. The grafting of styrene onto cellulose diacetate was kinetically followed with particular attention paid to the polystyrene molecular weight behavior. The molecular weight was evaluated with the polymer fractions obtained by acid hydrolysis of the grafted copolymer. From the experimental results it appeared that the grafted chain molecular weight is completely controlled by the physical properties of the polymeric matrix either during a “bulk” or a “front
