摘　　要：以含活泼叔氢原子的甲基丙烯酸丁酯-丙烯酸丁酯共聚物(poly(BMA-co-BA))为基质聚合物,过氧化苯甲酰(BPO)为引发剂,甲基丙烯酸羟乙酯(HEMA)为反应单体,基于反应挤出机理,制备改性甲基丙烯酸丁酯-丙烯酸丁酯共聚物熔体,同时采用熔融纺丝法制备纤维,在冷却固化过程中,将基于氢键和缠结作用的物理交联结构赋予纤维,使其具备吸油功能。研究纤维的吸油性能、耐油品溶解能力以及其它性能,并借助相关仪器对纤维的结构进行表征。结果表明,增加HEMA添加量或BA投料量均会提高所得纤维抵御油品溶解的能力,当基质聚合物相同时,在相同的吸油时间下,随HEMA添加量的增加,所得纤维的吸油量增大,BA投料量较高时所得纤维对三氯乙烯的最大吸油量可达7.1g/g,对四氯乙烯的最大吸油量可达8.A mechanism of reactive extrusion was adopted to prepare the melt of modified poly（butyl methacrylate-co-butyl acrylate）when the copolymer of butyl methacrylate and butyl acrylate containing active tertiary hydrogen atoms was used as matrix polymer,and benzoyl peroxide and hydroxyethyl methacrylate were used as initiator and reactive monomer,respectively.Then the melt was spun into fiber via melt spinning.In the process of cooling solidification,the fiber was endowed with physical crosslinking structure based on hydrogen bonding and entanglement,and the fiber subsequently had the function of oil absorption.Thereafter,its oil absorption,the capability to resist oil,and other properties were investigated;additionally,its structure was characterized by using corresponding instruments.The results show that the fiber＇s capability to resist oil can be improved when the addition amount of HEMA or the feed amount of BA increases.In addition,at the same absorption time,the oil absorbency of the fiber increases with increasing the content of HEMA when the same matrix polymer is used,and the maximum oil absorbency of the fiber which is prepared from the copolymer synthesizes with more BA monomer is 7.1g/g for trichloroethylene and 8.0g/g for tetrachloroethylene.
