马来酸酐酯化丙烯酸酯接枝淀粉浆料的研究

Study on Maleic Anhydride Esterification Acrylate Graft Starch Size Mixture

探讨接枝单体对马来酸酐酯化预处理型丙烯酸酯接枝淀粉浆料性能的影响。将马来酸酐酯化淀粉分别与丙烯酸甲酯、丙烯酸乙酯及丙烯酸丁酯进行接枝共聚合反应,制备出马来酸酐酯化预处理型丙烯酸酯接枝淀粉浆料,并测试了各接枝淀粉浆料的接枝效率、接枝率、单体转化率、黏度、黏度热稳定性、黏附性能及浆膜性能。试验结果表明:丙烯酸乙酯较适宜作为制备马来酸酐酯化预处理型丙烯酸酯接枝淀粉浆料的接枝单体。

Effect of graft monomer on maleic anhydride esterification acrylate graft starch size mixture property were discussed. Maleic anhydride ester starch was grafted and copolymcrized with methacrylate,ethyl acrylate and butyl acrylate respectively. Graft efficiency, graft rate, monomer conversion rate, viscosity, viscosity thermal stability,adhesion per- formance and size film property of each graft starch were tested. The test shows that ethyl acrylate is the suitable graft monomer of manufacturing maleic anhydride esterification acrylate graft starch size mixture.
