摘要:
研究海藻酸钙水凝胶与乙酸乙烯酯(VAc)的接枝共聚反应的影响因素,探讨引发体系和引发剂的用量、分散剂和单体的用量、反应温度和反应时间对接枝率的影响.当5g的海藻酸钙水凝胶加入4mL质量分数为0.03的聚乙烯醇,在0.28g过硫酸铵引发下,与7mL的醋酸乙烯酯单体在50℃下反应3h,接枝率最大可达1927%.最后,用红外光谱对其结构进行表征.
Abstract:
Regarding the graft copolymeriation of vinyl acetate onto calcium alginate aquagel, the authors dealt with the influencing factors. An inquiry was made into the effects of various factors on grafting percentage, these factors include initiation system and dosage of initiator, dosage of dispersing agent and monomer, reaction temperature and reaction time. A maximum grafting percentage up to 1 927% had been attained when 5 g calcium alginate aquagel was added in 4 mL of 3% polyvinyl alcohol and was reacted with 7 mL of vinyl acetate monomer at 50 ℃ for 3 hrs under the initiation of 0.28 g ammonium presulfate.
