Abstract : The paper outlines research findings on a project involving the elucidation of the process of radiation-induced graft polymerization of monomer to polymer. The quantitative interrelationships of the initiation rate, the k(p)/(k(+) to the 1/2 power) ratio for the monomer, the equilibrium solubility of the monomer in the polymer, the polymer film thickness, the reaction time, and the diffusivity of the monomer in the polymer were investigated. Work on the project has given a mathematic analysis of the grafting reaction and its exact dependence on these factors. Equations show quantitatively how the various parameters in any grafting system interact to lead to diffusion-controlled graft polymerization.
