Influence of spacer group on the structure and thermal properties of copolymers based on acrylonitrile and methacrylic 1,3-thiazole and 1,2,3-triazole derivatives

摘要: Abstract The influence of spacer group on the binomial relationship between structure and thermal properties has been studied in different copolymeric families, considering insertion either mono or bisheterocyclic pendant groups, as well ratio comonomers. In consequence, six systems based acrylonitrile methacrylic monomers bearing 1,3-thiazole 1,2,3-triazole P(AN- co -MTA), have synthesized with compositions by free-radical polymerization anhydrous DMSO solution at 60 °C. These copolymers analyzed size exclusion chromatography (SEC), Elemental Analysis CHNS, infrared spectroscopy (ATR-FTIR) wide-angle X-ray diffraction (WAXS). behavior also examined differential scanning calorimetry (DSC) thermogravimetric analysis (TGA). Gordon–Taylor–Wood equation used to fit glass transition temperature variation a function weight molar fraction copolymer.
