Abstract

The miscibility occurs in the poly(styrene-co-acrylonitrile)(SAN)/poly(benzyl methacrylate)(PBzMA) blends if AN wt% in SAN is within a window range of 3-25 wt%, is demonstrated. The k (G-T parameter for the SAN/PBzMA blends versus AN content (3.5-24.4 wt%) in SAN exhibits a convex curve and the value of k is the maximum near AN = 7-10 wt%. In general, for the miscible SAN/PBzMA system, no evidence of specific interactions between the binary constituents is found and their miscibility window behavior all complied with the concept of matching polarity between the SAN copolymers and polymers in terms of solubility parameters.
