摘　　要：研究了温度、乳化剂浓度、引发剂浓度和单体浓度与BA/AN/MA三元乳液共聚合的动力学行为的关系;考察了温度、乳化剂浓度、引发剂浓度及分子量调节剂对三元共聚物特性粘数的影响;对共聚物的结晶性及微观结构用宽角X射线衍射、红外光谱和核磁共振氢谱进行了表征。The relationships between Butylacrylate/Acrylonitrile/Methylacrylate triad emulsion polymerization kinetics and temperature, initiator concentration and total monomer concentration were researched. The effects of temperature, initiator concentration, emulgent concentration and thioalcohol concentration on intrinsic viscosity of copolymers were investigated. The crystallinity and microstructure of copolymers were characterized by means of wide angular X ray diffractogram, infrared spectrogram and 1HNMR spectrogram.
