white to light yellow powderSynthesis
Poly(vinyl cinnamates) (PVCi) can be prepared by esterification of the hydroxyl group in polyvinyl alcohol (PVA) and the carboxyl group in p-chlorocinnamic acid. All grafting modification was carried out in a four-necked flask equipped with a mechanical stirrer, con denser, and nitrogen inlet. PVA was dissolved in DMSO (5 wt% solution) at 80℃, certain amounts of cinnamic acid was added in PVA solution, the reaction mixture was stirred at 35℃ for 24 h with the catalysis of DCC and DMAP. At the end of the reaction, the product was precipitated twice in ethanol to completely remove the solvent. Then the product was purified by removing the unreacted cinnamic acid in extractor with ethanol and then dried under vacuum at 30℃ for 24 h. The modified PVCi was completely insoluble in water in which PVA had been freely soluble before graft modification. The DS was controlled by adjusting the molar ratio of cinnamic acid to the hydroxyl groups.
