摘要
采用乳液接枝共聚方法,合成了氧化淀粉-甲基丙烯酸甲酯-丙烯酸乙酯-丙烯酸接枝共聚物乳液,并用该乳液制备了新型酯溶性可降解港宝化学片。试验结果表明合成共聚乳液的最佳条件为:氧化淀粉添加量为单体质量总量的15%,m(MMA):m(EA):m(AA)=75:22:3,m(十二烷基硫酸钠):m(烷基酚聚氧乙烯醚)=1:2,乳化剂用量为3·0%,引发剂用量为0.6%,温度为80℃。研制出的新型酯溶性可降解港宝化学片邵氏D硬度为53,黏合强度为7N·mm-1,拉伸性能为13MPa,酯溶性为57%。
The amount of oxidized startch was 15% of the monomers. The oxidized stanch - g - MMA - EA - AA copolymer was synthesized by emulsion graft copolymerization, and then a new type of acetate - soluble degradable toe puff was developed based on the above emulsion. The optimum reaction conditions for polymerization are as follows: m(MMA):m(EA):m(AA) = 75 : 22 : 3 ; the emulsifier system is adapted as m ( sodium dodecyl sulfate) : m ( alkylphenol ethoxylates ) = 1 : 2 with 3.0% of all monomers ; the ratio of initiator is 0.6% ; and, the polymerization temperature is 80℃. The Shore D hardness of the new acetate - soluble degradable toe puff is 53, its adhesive strength and tensile property are 7 N1mm^-1 and 13 MPa respectively. The developed acetate - soluble copolymer is dissoluble in related solvent with a 57% soluble ratio.
