摘要
采用超临界萃取分离聚丙烯酸盐中的单体,对影响萃取分离效率的三个主要因素:温度、压力、改性剂进行了筛选,建立了测定聚丙烯酸盐中单体含量的分析方法,此法标准物添加回收率为932%~948%。
Residual monomer in polyacrylate resin is separated by supercritical fluid extraction(SFE)and factors,temperature,pressure and modifier,having influence on the extraction were selected Then a method for monomer determination was established with a recovery of 93 2%~94 8%
