AM-AHPTAC共聚及其竞聚率测定

以3-丙烯酰氧基-2-羟丙基三甲基氯化铵（AHPTAC）与丙烯酰胺（AM）为单体，以（NH4）2S2O8-NaHSO，作引发剂，在40℃水中通过溶液聚合法合成了阳离子共聚物，并通过IR、^1H-NMR对其结构进行了表征。采用AgNO3滴定方法，测定了共聚物的阳离子度，然后用截距斜率法（Fineman-Ross法）测得AM、AHPTAC两单体的竞聚率分别为r1=10．90，r2=0．14；直线交叉法测得AM、AHPTAC竞聚率分别为r1=10．94±0．20，r2=0．15±0．04。...

Using 3-acryloxy-2-hydroxypropyl-trimethylammonium chloride （AHPTAC） and acrylamide （AM） as raw materials, the cationic copolymer was synthesized in aqueous solution at 40℃ with ammonium persulfate and sodium hydrogen sulfite as redox initiators. The structure of the cationic copolymer was identified by IR and ^1H-NMR. The cationic density of cationic eopolymer was determined by AgNO3 solution titration. Monomer reactivity ratios r~, r2 for AM and AHPTAC were,respectively, r1 = 10.90,r2 =0. 14 by the Fineman-Ross method; r1 = 10.94±0.20,r2 =0.15 ±0.04 by the method of point of intersection.
