摘要:

在C18DMAAC和AM两种单体的基础上引入含有芳香基团的单体苯乙烯,得到AM/C18DMAAC/Styrene三元共聚物,主要来考察链刚性的增加对聚合物的溶解性、耐温抗盐性、抗剪切性以及临界缔合浓度的影响。研究表明随着链刚性的增加聚合物的溶解性能略有下降,而耐温抗盐性能以及抗剪切性明显增加,同时链刚性增加可以使疏水缔合聚合物的临界缔合浓度降低,并且链刚性越大二临界缔合行为越明显。说明链刚性的增加对疏水缔合聚合物性能改善作用显著。

Abstract:

Based on AM and C18DMAAC,styrene which contains aromatical phenyl is induced and AM/C18DMAAC/styrene gained, the influence of chain stiffness on resolvability,temperature resistance,salt tolerance,resilience of shearing resistence and critical associating concentration reviwed.With the chain stiffness increasing,resolvability decreases apparently,the other performances increase.Increase of chain stiffness can decrease critical associating concentration of Hydrophobic associating water-soluble polymer(HAWP).Chainstiffness is stronger,the hydrophobic associating behavior is more obvious.HAWP can increase its performance through chain stiffness.

Key words: hydrophobic associating water-soluble polymer, chain stiffness, critical associating concentration, resolvability, temperature and salt resistance performance
