摘　　要：针对目前吸油材料吸油倍率低、吸油速度慢的问题,提出核壳结构的高分子吸油微球,以丙烯酸丁酯和丙烯酸十二脂为聚合单体、二乙二醇二丙烯酸酯为交联剂、偶氮二异丁腈为引发剂,采用悬浮聚合法制备了高分子吸油微球,然后以二乙烯基苯和苯乙烯为单体在高分子吸油微球表面制备了表层结构,制备了核壳状高分子吸油微球,并考察里、表层单体及比例、交联剂种类和用量、引发温度等因素对吸油性能的影响,核壳微球的吸油倍率可达29倍,饱和吸油时间为3min,吸油速度大大提高。The core structure of absorbent polymer particle was synthesized by suspension polymerization using n-butyl acrylate and nLaurylacrylate as monomers,diethylene glycol diacrylate as cross-linking agent,2,2′-Azobis(2-methylpropionitrile)as initiator.Then,the shell structure was synthesized at the outer surface of the polymer particle using divinylbenzene and phenylethylene as monomers.The effects of the ratio of monomer amounts of core to that of shell,the category and amount of cross-linking agent and initiation temperature on the absorbent ability were studied.The oil absorbent polymer particle with core-shell structure was synthesized with the absorption capacity of 29g/g.Saturation absorption time of the absorbent polymer particle with core-shell was 3min,and it was markedly faster than that without core-shell structure.
