Abstract

Solid-state shear pulverization (SSSP) has been shown to achieve compatibilization of immiscible polymer blends by the in situ formation of block copolymer resulting from coupling of polymer radicals made via low levels chain scission. Here we describe the impacts of microscopic dispersion of a blend prior to SSSP, processing aids (trace levels of polyethylene wax), and various SSSP process parameters on the ability to achieve intimate mixing as well as compatibilization. These studies also reveal that optimization of SSSP of polymer blends can result from focusing on only several of the many SSSP processing variables.
