Abstract

The miscibility behaviour of poly(chloromethyl methacrylate) (PCMMA) and poly(2-chloroethyl methacrylate) (PCEMA) with various aliphatic polyesters was studied by differential scanning calorimetry. PCMMA and PCEMA are miscible with poly(ethylene adipate), poly(butylene adipate), poly(hexamethylene sebacate) (PHS), poly(2,2-dimethyl-1,3-propylene succinate) and poly(2,2-dimethyl-1,3-propylene adipate). In addition, PCMMA is miscible with poly(ethylene succinate) whereas PCEMA is not. Blends of PCEMA with poly(2,2-dimethyl-1,3-propylene sebacate) exhibit upper critical solution temperature behaviour. Interaction parameters for PCMMA/PHS and PCEMA/PHS blends were evaluated from melting point depression analysis.
