【摘要】 以轻度脱氯化氢的聚氯乙烯(PVC)、丙烯酸丁酯(BA)、二乙烯基苯(DVB)为原料,采用悬浮溶胀接枝共聚的方法合成一种新型高吸油性树脂。研究了BA含量、DVB用量、过氧化苯甲酰(BPO)用量等因素对其吸油性能的影响。该树脂对含氯的有机溶剂具有较高的吸附性,最高可吸三氯甲烷38g/g,氯苯31g/g。其对甲苯等其它有机溶剂的吸附性能与烷基丙烯酸酯型低交联吸油树脂的吸油性能相当。更多还原

【Abstract】 A new high oil-absorbent of slightly dehydrochlorinated PVC-butyl acrylate- Divinylbenzene copolymer were synthesized by suspension-swelling graft copolymerization. The effects of the amount of butyl acrylate (BA), divinylbenzene (DVB) and benzoyl peroxide (BPO) etc on the oil absorbency of the resin were studied respectively. This resin has a good absorbency with the organic chlorohydrocarbon solvent, for example, Chloroform 38 g/g, chlorobenzene 31 g/g. As the other hydrocarbon solvent, its absorbency can be comparable with the lower cross-link alkyl acrylate resin.更多还原
