โœฆ Synopsis

The miscibility of random copolymers of bisphenol-A polyarylate and tetramethyl bisphenol-A polyarylate (PAr-co-TMPAr) with poly(styrene-co-acrylonitrile) (SAN) was studied based on the glass transition behaviour measured by differential scanning calorimetry. Analysis of the miscibility map by using the mean field theory showed that the intramolecular repulsion between styrene and acrylonitrile units in SAN gives a large contribution to the miscibility of PAr-co-TMPAr and SAN.
