以过氧化苯甲酰为引发剂,采用沉淀聚合法合成了苯乙烯-马来酸酐交替共聚物,用核磁共振（13C-NMR）,红外光谱（IR）和凝胶渗透色谱（GPC）对共聚物进行了表征。利用苯乙烯-马来酸酐交替共聚物的水解反应制备了苯乙烯-马来酸交替共聚物,并对其水溶液性质进行了研究。结果表明,苯乙烯-马来酸交替共聚物为二元羧酸,且随着共聚物浓度的降低,其比浓黏度迅速增加,在同一浓度下,随着溶液pH值升高,水溶液黏度先增大后减小,当pH值达到6时,溶液黏度达到最大值。
Styrene-maleic anhydride copolymer（SMA） was synthesized by solution sediment polymerization method,with benzoyl peroxide（BPO） as the initiator.The structure of the copolymer was confirmed by 13C nuclear magnetic resonance spectrum（13C-NMR）,infrared spectrum（IR） and gel permeation in chromatography（GPC） analysis.Styrene-maleic acid alternating copolymer（HSMA） was synthesized by the free radical polymerization-hydrolysis method,its solution property and influence factors were investigated.The experimental results indicate that HSMA is a binary carboxylic acid,and the solution viscosity increases when the concentration of copolymer decreases.At the same concentration,with the increase of the pH value of the solution,the viscosity of the solution increases at first and then decreases.The viscosity reaches the maximum value when the pH value of the solution is 6.
