The process of radiation grafting of vinylalkoxysilanes, monomers inactive in free-radical polymerization, onto PP was studied. The effects of the chemical structure of vinylalkoxysilanes and their sorption-diffusion characteristics, as well as irradiation parameters on the efficiency of radiation grafting were assessed. Based on the data obtained, the experimental conditions which make it possible to exclude the diffusion control of the process were determined. It was shown that the hydrolysis of alkoxy groups of vinylsilanes radiation-grafted onto PP provides a means of obtaining structured PP with a desired content of gel fraction.
