摘　　要：以质量分数为33.0%二甲胺水溶液、氯丙烯为原料,合成中间体二甲基烯丙基胺,然后以溴代十六烷与二甲基烯丙基胺为原料,通过季铵化反应合成了一种疏水性季铵盐单体ADMA-16。并以AM、DMC与ADMA-16为反应单体合成了一种三元疏水缔合聚合物PADA。通过测定PADA溶液的表观黏度优化PADA的合成条件,研究PADA的耐温抗盐性能。结果表明,PADA的临界缔合浓度为0.33%。聚合物PADA表现出一定的耐温抗盐性。The intermediate dimethylallylamine was synthesized from dimethylamine aqueous solution with mass fraction of 33.0%and propylene chloride.Then a hydrophobic quaternary ammonium salt monomer ADMA-16 was synthesized by quaternization reaction of hexadecane bromide and dimethylallylamine.A ternary hydrophobically associating polymer PADA was synthesized by using AM,DMC and ADMA-16 as reaction monomers.The synthesis conditions of PADA were optimized by determining the apparent viscosity of PADA solution,and the temperature and salt resistance of PADA were studied.The results showed that the critical association concentration of PADA was 0.33%.Polymer PADA exhibits certain temperature and salt resistance.
