Miscibility of poly(tetrahydrofurfuryl methacrylate) and poly(tetrahydropyranyl-2-methacrylate) with some chlorine-containing polymers

Abstract

The miscibility of poly(tetrahydrofurfuryl methacrylate) (PTHFMA) and poly(tetrahydropyranyl-2-methacrylate) (PTHPMA) with some chlorine-containing polymers was studied by differential scanning calorimetry (DSC). PTHPMA was found to be miscible with poly(vinyl chloride) (PVC), polyepichlorohydrin (PECH), and a vinylidene chloride/vinyl chloride copolymer [P(VDC/VC)] and only partially miscible with an epichlorohydrin/ethylene oxide copolymer [P(ECH/EO)]. PTHFMA was shown to be miscible with PECH and P(VDC/VC), but its miscibility with P (ECH/EO) is composition-dependent. Information about interactions between components in PTHFMA/P(VDC/VC) and PTHPMA/P(VDC/VC) blends was estimated from melting-point depression. The interaction parameters B were found to be -1.7 and -3.6 J/cm3 PTHFMA/P(VDC/VC) and PTHPMA/P(VDC/VC) blend systems, respectively. The miscibility behavior of PTHFMA and PTHPMA is compared to that of poly(cyclohexyl methacrylate).
