自乳化微乳液法两亲水溶性聚合物的制备及性能
|
摘要
通过自乳化微乳液聚合的方法,以丙烯酰胺(AM)、丙烯酸(AA)、苯乙烯为原料(St),制备出两亲水溶性聚合物,避免了传统的微乳液聚合中引入过多小分子乳化剂而导致后期处理过程复杂的问题,同时对自乳化微乳液聚合机理进行探讨。红外和核磁结果表明:丙烯酰胺与丙烯酸和苯乙烯发生了共聚反应。DSC结果表明:生成的共聚物为嵌段结构。表面张力和黏度测试结果表明:当单体配比为m(AM)∶m(AA)∶m(St)=87.5∶10.0∶2.5时,其表面张力和黏度可达26.113 mN/m和1260 mPa·s,并解释了不同含量疏水单体存在时,溶液中分子链的聚集状态。
A self-emulsification microemulsion method was used to prepare an amphiphilic water-soluble polymer using acrylamide(AM), acrylic acid(AA) and styrene(St) as raw materials. This preparation method avoids the problem that too many small molecule emulsifiers are introduced into the traditional microemulsion polymerization, which leads to the complex post-processing process. In addition, the mechanism of self-emulsified microemulsion polymerization was discussed. FTIR and 1 HNMR results showed that the copolymerization of AM, AA and St was carried out. The DSC result revealed that the obtained copolymer was a block structure. The results of the surface tension tester and the numerical viscosity test showed that when m(AM) : m(AA) : m(St) was 87.5 : 10.0 : 2.5, the surface tension and viscosity of the prepared copolymer solution were 26.113 m N/m and 1260 m Pa·s, respectively. Furthermore, the molecular chain aggregation state of the copolymer with different content of hydrophobic monomer in solution was explained.
