Time-Resolved Light Scattering Studies on L-L Phase Separation and Interchange Reaction induced Homogenization in Extruded PET/Phenoxy Blend

摘要

Binary polymer blends, which can undergo exchange reactions in the melt, have received considerable academic and industrial attention in recent years [1]. The result of "exchange reaction", "transesterification", or "interchange reactions", as they are often called, is the formation of block/random copolymers from the original binary pair. These block/random copolymers have a homogenizing effect on the blend, which enhanced the miscibility between components leading to a single phase blend [2-6].
