ABSTRACT
The requirement of biocompatible properties of the material often negates the use of a plastic that otherwise has excellent physical and processing properties. Graft copolymerization is one method of polymer modification that can build additional properties into the polymer without totally eliminating the desirable properties of the parent polymer. Monomer purification was carried out by either vacuum distillation or by pouring the monomer through a column containing amberlite which specifically absorbs any inhibitors present in the monomer. Mutual irradiation grafting experiments were carried out in glass ampules which had been fitted with O-ring glass joints through which the grafting solution could be introduced. A laboratory extruder which had been fitted with a crosshead die was used in experimental tube preparation. A visual test has been devised for quick determination of the properties of the grafted samples in terms of their wettability following grafting.
