Abstract

Crystallization of poly(ethyleneoxide) (PEO) in blends with poly(methylmethacrylate) (PMMA) was investigated by a differential scanning calorimeter (DSC). The heat of melting, ΔHm, and the activation energy for crystallization, Ea, depended on PMMA tacticity. The crystallization rate became slower with increasing molecular weight of PMMA.
