Nuclear magnetic resonance (NMR) imaging (MRI) was applied to study the penetration of aggressive fluids, used as blowing agents for thermal insulators (polyurethane). The penetration profiles of cyclopentane and fluorotrichloromethane (Freon 11©) w

Blends of styrene/acrylonitrile copolymers (poly-SAN) with imidized PMMA exhibit increased thermoresistance in comparison with poly-SAN alone. The miscibility of two modified poly(methyl methacrylate) (PMMA) with poly-SAN has been evaluated with the

A direct determination of enthalpy of mixing (ΔHmix) is of interest in predicting miscibility in polymer—polymer systems. Such measurements present, however, working difficulties, so a reliable indirect approach has been attempted. The enthalpy of

Solid-Liquid equilibria for e-caprolactam and its oligomers have been studied to evaluate the solubility limits for dimer, m the temperature range of (90–120)°C and trimer at 90°C, by experimental determination of mixing enthalpies ΔHmix at P =
