Diffusion-controlled polymer-polymer reactions in bulk: Novel strategy for model experiments and reactive compatibilization using polymers synthesized via controlled radical polymerization

The strategy for reactive compatibilization using polymers synthesized through controlled radical polymerization (CRP) was discussed. Diffusion-controlled interpolymer reactions were useful in reactive processing and compatibilization of immiscible blends in which interpolymer reactions yielded block or graft copolymers. Results showed that polymers made through nitroxide-mediated (NM)-CRP could undergo efficient interpolymer radical-radical coupling at conditions amenable to model studies and reactive compatibilization.
