Description
Summary:The novel chalcone modified poly (styrene) based polymer (PVBC-DMAC) has been prepared and characterized. By using the inverse gas chromatography method, we determined glass transition temperature and surface properties of PVBC-DMAC. The obtained glass transition temperature, Tg, is a good agree with the one obtained by differential scanning calorimetry. Also considering some isomeric alcohol and acetate solvents in the temperature range from 303.2 K to 353.2 K, we investigated the polymer selectivity. The parameters KA(acidic) and KD(basic) of the PVBC-DMAC surface were calculated. The obtained KA, KD values reflected that PVBC-DMAC surface has a basic character. nema
