丙烯酸类单体以共价键形式与胶原多肽主链结合,用DSC、TG和XRD等测试手段表征了接枝共聚物的结构和性质。探讨了单体滴加方式和预乳化对反应产物乳液稳定性的影响,研究了接枝率和接枝效率随胶原浓度、单体总量、反应温度和反应时间的变化规律。当胶原浓度为15%、单体总量/胶原质量为60%、保温反应1h且丙烯酸类单体AA、AM、BA和AN质量比为5?1?1?1时,丙烯酸类单体的接枝率可达48.64%。 The acrylic monomers were covalently bonded to the collagen peptide backbone. The structures and properties of the graft copolymers were characterized by means of DSC, TG and XRD. The effects of monomer addition mode and pre-emulsification on the emulsion stability of the reaction product were discussed. The variation of graft ratio and graft efficiency with the concentration of collagen, total monomer, reaction temperature and reaction time were studied. When the concentration of collagen is 15%, the total amount of monomers / collagen is 60%, the reaction time is 1 h and the mass ratio of AA, AM, BA and AN of acrylic monomer is 5? 1? 1? Grafting rate up to 48.64%.
