The graft copolymerization of aerylonitrile onto Chinese southern pine SGW using KMnO₄ as initiator has been carried out to evaluate the effect of lignin on the grafting. It is found that the inhibiting action of lignin might be caused by its phenol structure unit. ln case the phenolic hydroxyls were etherified by propylene oxide the copolymerization was going smoothly: The basic grafting conditions of hydroxypropylated SGW were studied. X-ray analysis showed that the copolymerization took place not only within the amorphous region but in the crystalline region as well, causing a certain degree of decrystallization in cellulose.
