CONTRIBUTION TO THE STUDY OF GRAFTED COPOLYMERS PREPARED BY RADIOCHEMICAL METHODS. II. KINETICS OF THE FORMATION OF THE GRAFTED COPOLYMER AND THE HOMOPOLYMER (in French)
The study of the radioehemical grafting of styrene on polyisobutylene was continued by examining the effect of factors such as the radiation dose, the radiation intensity, and the initial concentration of the polyisobutylene on the formation of the gratted copolymer and the homopolymer. Although they are produced in the same reacting medium, the reactions of homopolymerization and of grafting have different kinetic characteristics. The classical laws of polymerization are followed by neither reaction. The interpretation of the results observed is based on the fact that the precipitation of the growing chains. resulting from the incompatibility of the polymers present during the grafting, leads to a coalescence or a gel effect according to the conditions.
