Abstract

Interpolymer radical coupling leading to block copolymer formation is demonstrated for the first time in the solid state and in the absence of diffusion using solid-state shear pulverization. Fluorescence-detection gel permeation chromatography detected interpolymer reaction in high-molecular weight polystyrene (PS)/pyrene-labeled PS and high-MW poly(methyl methacrylate) (PMMA)/pyrene-labeled PS blends. Proof of interpolymer radical coupling supports prior pulverization studies demonstrating compatibilization, i.e., stability of dispersed-phase to long-time annealing, of PS/high density polyethylene and PS/PMMA blends.
