✦ Synopsis

The miscibility of polymethyl methacrylate (PMMA) with the poly (hydroxy ether) of bisphenol A (phenoxy resin) was studied and PMMA has been found to be miscible with phenoxy resin. PMMAlphenoxy blends were found to be clear and showed a single, composition-dependent glass transition temperature. The k parameter of the Gordon-Taylor equation can be taken as a measure of the strength of the specific interaction between the two polymers, and a low value of k = 0.3 is found for the PMMA/Phenoxy blends. Fourier transform infrared ( F T I R ) showed the presence and nature of intermolecular interactions between the two polymers.

## Abstract Poly(methyl methacrylate) (PMMA) and bisphenol‐A polycarbonate (PC) are important commerical polymers. PMMA/PC blends were once considered as immiscible blends.^1–3^ However, recent studies have shown that the miscibility of PMMA/PC blends depends on the method of preparation.^4–8^ Chio
