摘要
本文用丙烯酸β-羧乙酯作为主要共聚单体,以偶氮二异丁腈及过氧化苯甲酰为引发剂,在丙酮溶剂中使之与苯乙烯进行自由基型溶液共聚合,研究了影响共聚合反应的主要因素,并在可控的低转化率条件下制得了丙烯酸β-羧乙酯含量不等的共聚物,以YBR法及电子计算机计算了共聚单体的竞聚率,得r_(st)=0.5863,r_(APA)=0.2826。
β-Acryloxypropionic acid and styreae copolymers were synthesized through radical copo-lymerization, using AIBN and BPO as initiators, acetone as solvent. The major factors that affected the copolymerization were studied and the copolymers with low conversion and different monomer feed ratio were synthesized. The copolymerization reactivity ratios were determined by YBR method and then calculated on a computor. The following data were obtained : r =0.5863, rApA=0.2826
