The phase behaviour of the system poly(2,6-dimethyl-1,4-phenyleneoxide) (PPO) - antracene was investigated. An eutectic behaviour was deduced from calorimetric observations. In samples prepared by evaporation of a benzene solution, the melting point

The expansion of polystyrene using water as the blowing agent has been investigated. Hydrophilic particles are dispersed in styrene before the suspension polymerization. During this polymerization the necessary amount of water is absorbed and/or adso

The phase behaviour of linear poly(N-isopropylacrylamide) (PNIPA) and chemically cross-linked PNIPA in water has been determined by calorimetric and optical techniques. Experiments for the linear polymer were conducted for three different molar masse

Calculations based on an extended Flory−Huggins−Staverman model demonstrate that miscibility gaps in virtually immiscible blends may encompass a complex pattern of metastable and unstable equilibria that differ little in Gibbs free energy. Exampl

It is demonstrated that the collapse of gels of radiation cross-linked poly(vinyl methyl ether) swollen in water is a truly discontinuous process obeying classic thermodynamic principles. The phenomenon can further be shown to be related to the relev

The morphology and thermal properties of a poly(styrene)-poly(ethylene, butylene) triblock copolymer in the presence of a selective solvent has been investigated, using small-angle X-ray scattering (SAXS) and calorimetry (d.s.c.). The temperature dep

The preparation of porous fibers from the quasi-ternary system poly(methyl methacrylate)/poly(ethyl methacrylate)-1-butanol is based on the combination of different liquid-liquid demixing processes that interfere with the vitrification process. Polym
