The study of Thermal Properties of Vinyl phosphonic acid/oligo ethylene glycol methyl methacrylate copolymeric organogels

This paper considers the examination of the thermal properties for synthesized copolymeric organogels from vinyl phosphonic acid (VPA) and oligo (ethylene glycol) methyl ethyl methacrylate (OEGMA, Mn=475) macromere. A constant amount of poly ethylene glycol dimethacrylte (PEGDMA, Mn=330) was used as a tetrafunctionalcrooslinker in preparation of these organgels. Thermo-gravimetric analysis of these samples have been shown thatwith increase of VPA percent char yield was increased but initial decomposition temperature (IDT) was decreased. DMTA analysis of these compounds was showed the glass transition temperature of the copolymers changes in the range of -47.4C for poly(OEGMA475) to 97.7C for poly(VPA).
