TL;DR: The theoretical and practical aspects of polymer-polymer miscibility in the solid amorphous state are reviewed in this article, where the polymers include homopolymers and both random and block copolymers.
Abstract: The theoretical and practical aspects of polymer-polymer miscibility in the solid amorphous state are reviewed. The polymers include homopolymers and both random and block copolymers. Although present theoretical treatments of polymer-polymer miscibility all contain the random mixing hypothesis and are thus not applicable to mixtures that involve specific interactions between the components, most of the observed singlephase polymer-polymer mixtures involve hydrogen-bonding or other specific interactions between the components. Even in the absence of specific interactions, the composition of a random copolymer can often be tailored to provide miscibility with a particular homopolyner. Many polymer-polymer mixtures have lower critical solution temperatures, and a small number of such mixtures have given indications of upper critical solution temperatures. The special phenomena that may be observed when other polymers are mixed with block copolymers are discussed.

TL;DR: In this article, the miscibility gap boundaries of Li2O and Na2O-SiO2 binaries are described by modified regular-mixing equations based on the concept that the thermodynamic mixing processes are controlled by complex but discrete molecular structures which exist in the melt.
Abstract: Measurements of the miscibility gaps in the Li2O- and Na2O-SiO2 binaries are reported and compared to data of other workers. Heat treatments by brief immersion in liquid Sn were used for measuring the properties of glasses with a strong devitrification tendency. The miscibility-gap boundaries of both systems are successfully described by modified regular-mixing equations based on the concept that the thermodynamic mixing processes are controlled by complex but discrete molecular structures which exist in the melt. The assumptions and implications of the model are discussed.

TL;DR: In this article, the effects of the O:W1 phase ratio on the morphology and size of microspheres were interpreted in terms of the solvent miscibility with water, as well as the influence of the W1 volume on breakup of the dispersed phase.

TL;DR: In this paper, the structure of binary blends of P[(R)-3-hydroxybutyric acid/P[(S)-LA] with various molecular weights (Mw = 9900-530 000) have been studied by means of differential scanning calorimetry.
