| Abstract: | 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. PMMA/phenoxy 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 (FTIR) showed the presence and nature of intermolecular interactions between the two polymers. |
