Radiation-induced grafting is a potential method for modification ofpolymers, for example, highly hydrated polymeric surfaces may be biocompatiblc andthomboresistant. It is well known that addition of mineral acid to some graftingsolution enhanced the radiation grafting yield of some polyolefins. But it turnsout not to be the case in all conditions. Some monomers(such as N-VP)can be graftedonto some polymers(such as SPEU)only in basic medium. That means that the acideffect in grafting systems depends on many...

Radiation-induced grafting is a potential method for modification ofpolymers, for example, highly hydrated polymeric surfaces may be biocompatiblc andthomboresistant. It is well known that addition of mineral acid to some graftingsolution enhanced the radiation grafting yield of some polyolefins. But it turnsout not to be the case in all conditions. Some monomers(such as N-VP)can be graftedonto some polymers(such as SPEU)only in basic medium. That means that the acideffect in grafting systems depends on many effects such as component of matrix, typeof monomers and solvents, method of irradiation, absorbed dose and so on. In thiswork, the cuves of grafting yield as a function of absorbed dose showed that therewere about two regions of dose: lower than 5 kGy, the grafting yield of AA on sili-cone robber was enhanced by acid; the other region, dose growing up to about 13kGy, the opposite results were obtained. In acid enhancing region of dose the tendencyof grafting yield as a function of dose rate and monomer concentration was notinfluenced by whether the acid existed. The mechanism was dtscussed as well.

A kinetic study was made on the preirradiation grafting of styrene onto cotton cellulose. The dependencies of the grafting yield on preirradiation (in air) dose, grafting reaction time and grafting temperature were investigated respectively. The grafting yields as a function of above reaction conditions weree xpressed by derived using approximate formulae. The results about the relation between the grating yields with these grafting conditions calculated by the equations derived in this work were con$1stent with respective experimental data. It means that the experimental results are correct and the derived equations are reasonable.
