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

摘要

AbstractThe 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 parametersBwere found to be −1.7 and −3.6 J/cm3for 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
