In the present paper we focus on the role that polymeric diluents play in determining the crystalline microstructure of melt-miscible blends. Model blends of poly(ethylene oxide) with two weakly-interacting [PMMA and poly(vinyl acetate)] and two strongly-interacting amorphous polymers [styrene-hydroxystyrene and ethylene-methacrylic acid random copolymers] were examined. Using primarily small-angle x-ray scattering, we have explored the influence of intermolecular interactions and diluent T{sub g} on the microstructure that develops at different crystallization temperatures. The crystallization kinetics and supermolecular structure of these materials have also been examined.
