“…Besides those for PCL/SAN blends, there have been many studies of miscibility of SAN with a homopolymer and a copolymer. It was previously reported that SAN is miscible with poly(methyl methacrylate) (PMMA),3–5 poly[styrene‐ co ‐(maleic anhydride)] (SMA),6–10 poly[(methyl methacrylate)‐ co ‐( N ‐phenylmaleimide)],11 and poly[styrene‐ co ‐( N ‐phenylmaleimide)] (SMI),10 when the AN content of SAN is within a specific range. It is believed that the miscibility of SAN with other polymers is mainly attributed to the thermodynamically unfavorable repulsion between St and AN segments in the random copolymer and, in general, there are no specific interactions between dissimilar chains 12–14…”

Dynamic viscoelastic properties for miscible blends of poly(⑀-caprolactone) (PCL) and poly(styrene-co-acrylonitrile) (SAN) were measured. It was found that the time-temperature superposition principle is applicable over the entire temperature range studied for the blends. The temperature dependency of the shift factors a T can be expressed by the Williams-Landel-Ferry equation: log a T ϭ Ϫ8.86(T Ϫ T s )/(101.6 ϩ T Ϫ T s ). The compositional dependency of T s represents the Gordon-Taylor equation. The zero-shear viscosities are found to increase concavely upward with an increase in weight fraction of SAN at constant temperature, but concavely downward at constant free volume fraction. It is concluded that the relaxation behavior of the PCL/SAN blends is similar to that of a blend consisting of homologous polymers. It is emphasized that the viscoelastic functions of the miscible blends should be compared in the iso-free volume state.

“…This is observed in mixtures where at least one of the components is a statistical copolymer; miscibility is restricted to a "miscibility window," that is, it takes place within a well-defined range of copolymer composition. For example, poly(styrene-co-acrylonitrile) (SAN) and poly(methyl methacrylate) form miscible blends for copolymer compositions in the range 9-39% acrylonitrile (59,60). Miscibility in these systems is not a result of specific interactions, but it is due to the intramolecular repulsive effect (61) between the two monomer units in the copolymer such that, by mixing with a third component, these unfavorable contacts are minimized.…”

One of the main goals of polymer scientists is to control the structure and morphology of multicomponent systems to produce materials with novel properties. Understanding the miscibility behavior of polymer–polymer blends is vital, and this requires a knowledge of thermodynamics and the ability to select appropriate methods for the determination of phase behavior. The article provides a brief introduction to some aspects of polymer–polymer miscibility.

“…These blends offer a somewhat higher heat distortion temperature than ABS and good processing characteristics [43][44][45]. The Vicat softening temperature of 100 C for ABS can be raised to 130 C by blending with PC.…”
