Crystallization and Structure Formation of Strongly-Interacting Polymer Mixtures:Poly(ethylene oxide) and Styrene-Hydroxystyrene Random Copolymers

摘要

A series of experimental studies of the final solid state microstructural and spherulitic crystallization of melt-miscible polymer blends based on poly(ethylene oxide) [PEO] have been undertaken in our lab.Our most recent time-resolved,simulations WAXD/DAXS experiments showed that a polydisperse PEO crystallized in two distinct stages,with the first dominant stage having an Avrami exponent approx 3,following by a second crystallization process at longer times with n approx 1.
