【摘要】 用自由基溶液聚合方法制备一系列苯乙烯－丙烯酸甲酯线型共聚物，用核磁共振仪测定了苯基在共聚物中的百分比．在该共聚物的四氢呋喃溶液中，用三氯乙酸汞在共聚物的苯环上进行亲电取代反应，得到可溶性汞化共聚物．由于这类汞化共聚物可溶于四氢呋喃、二氯甲烷等溶剂，用重沉淀法（Ｒｅｐｒｅｃｉｐｉｔａｔｉｏｎ）多次提纯，得到了纯度很高、溶解性较好的含重金属二价录的共聚物．用红外光谱仪测定共聚物上的汞基因，用原子吸收仪定量测试共聚中的汞的百分取代率．结果表明在本文实验条件下，二价示可取代在苯环上，与丙烯酸甲酯基因没有作用．更多还原

【Abstract】 Linear copolymers of methylacrylate and styrene were prepared in ben.zene using AIBN as initiator. The linear copolymers were mercuriated by mercury (Ⅱ) trifluoroacetate in THF solution and purified by reprecipitating in distilled water from the THF solution. The mercuriated soluble copolymers loading mercury (Ⅱ) were charaterized by IR, NMR and atomic absorption analysis and the result indicated that the mercury reagent substituted the protons of the phenyl residues and had no reaction with the esther residues under the condition of mercuriation.更多还原
