Abstract
A novel radiation grafting method for modifying polymers of use in biomedical work is discussed. The procedure involves the use of particular inorganic salts as additives for accelerating the radiation grafting process. Styrene is used as typical monomer in these studies with cellulose, the polyolefins and PVC as representative backbone polymers. Two radiation grafting techniques are examined, namely pre-irradiation and simultaneous methods. The parameters affecting the observed grafting enhancement in the presence of these salt additives are treated. The results are compared with analogous data previously obtained with other additives, including acids. A new model for the mechanism of enhancement in radiation grafting in the presence of acids and/or salts is proposed. A typical biomedical application of the salt grafting technique for enzyme immobilization is briefly discussed.
