中文摘要：

先采用悬浮聚合合成含活泼叔氢原子的甲基丙烯酸丁酯一丙烯酸丁酯共聚物，然后以其为基质、以纳米级碳酸钙为填充组分、以甲基丙烯酸羟乙酯为反应性单体、以过氧化苯甲酰为引发剂，采用反应挤出法制备了包裹有刚性碳酸钙的新型功能树脂，并用热重分析仪、FESEM、XRD等方法对树脂的结构和性能进行表征，研究了酸处理前后树脂吸油性能和碱处理前后树脂的吸染料性能。结果表明，树脂的吸油能力几乎不受酸处理的影响，循环吸收时间达到50—60min时，树脂可将水中的泵油全部吸收，完成油水分离；与未碱处理样品相比，碱处理30min所得样品吸附阳离子蓝染料的能力显著提高。

英文摘要：

An active tertiary hydrogen atom containing poly （butyl methacrylate-co-butyl acrylate） was firstly synthesized via suspension polymerization, and then a novel functional resin containing rigid calcium carbonate was prepared by reactive extrusion while poly （butyl methacrylate-co-butyl acrylate）, nano-calcium carbonate, hydroxyethyl methacrylate and benzoyl peroxide were used as matrix polymer, filler, reactive monomer and initiator, respectively. The corresponding structure and properties of the prepared resin were characterized by using thermogravimetric analyzer, field emission scanning electron mi- croscope and X-ray diffractometer. The oil absorption of the resin before and after acid treatment and the capability of the resin before and after alkali treatment to absorb cationic blue dye were investigated in detail. The results show that acid treatment can not affect the oil absorption of the resin, and the resin can completely remove oil from water through absorption when circulating absorption time reached 50-60 min; additionally, the composite after alkali treatment for 30 min has good capacity to absorb cationic blue dye in comparison with the untreated ones.
