Synthesis and Characterization of Poly（ N-Vinyl-2-Pyrrolidone／Itaconic Acid） Hydrogel-中国Betway体育网页登陆

摘要 WithN-vinyl-2-pyrrolidone(NVP)anditaconicacid(IA),poly(N-vinyl-2-pyrrolidone/itaconicacid)[P(NVP/IA)]hydrogelwassynthesizedbyfreeradicalsolutionpolymerization.ThestructureofthisP(NVP/IA)wascharacterizedbyIR.Effectsofconcentrationofitaconicacid,amountofcross-linkagent,N,N′-methylene-bis-acrylamide,reactiontemperature,andtimeonpropertiesofswellingratio(SR)ofthehydrogelwereinvestigated.Theresultsshowthatthebestswellingpropertyofthehydrogelisobtainedat50℃and1.5h.pHsensitivityincreasesastheconcentrationofitaconicacidinthehydrogelsystemincreases.Swellingratioofthehydrogeldecreasesastheamountofcross-linkagentincreases.
