摘要
采用自由基胶束聚合法合成了丙烯酰胺(AM)/丙烯腈(AN)/烯丙基(对-壬基)苯基醚(ANPE)疏水缔合型水溶性共聚物,考察了温度、盐度和剪切时间对聚合物溶液表观粘度的影响。结果表明,所合成的AM/AN/ANPE三元共聚物的临界缔合质量浓度为4.39g/L,具有较好的抗盐、抗温及抗剪切性。
Hydrophobic association of AM/AN/ANPE ternary copolymer was successfully synthesized by micellar copolymerization.The effect of temperature,salinity,and shearing time on the apparent viscosity of copolymer solution was investigated.The results showed that the critical association concentration for the AM/AN/ANPE copolymer is 4.39 g/L,and the copolymer solution had good salt tolerance,heat resistance,and ability of shear resistance.
