【摘要】 合成了乙酸乙烯酯／顺丁烯二酸酐（ＶＭ）共聚树脂。通过ＮａＯＨ水溶液水解、ＣａＣｌ２交联，制备了ＶＭ树脂凝胶。研究了合成条件对ＶＭ树脂的产率、吸水率及保水率的影响。结果表明，当偶氮二异丁腈用量为１．４％、甲苯与单体的体积比为４～５∶１、顺丁烯二酸酐与乙酸乙烯酯摩尔比为１∶１．０１时，所合成的树脂产率最高、凝胶的吸水性能和保水性能最好。红外光谱分析表明，所合成的树脂是顺丁烯二酸酐与乙酸乙烯酯的共聚物。更多还原

【Abstract】 Vinyl acetate-maleic anhydride copolymer(VM) was synthesized.The crosslinked VM was prepared by hydrolization of VM with NaOH-H 2O solution and cross link of VM with CaCl 2-H 2O solution.The conversion absorption water ratio and preservation water ratio of VM were studied.The results shows that conversion,absorption water ratio and preservation water ratio of VM were best when z,z′-Azobisisobutyronitrile was 1.4%,volume fration of toluene was 80～85%,mole fration of vinyl acetate was 50.2% and CaCl 2 was 10%.更多还原
