| 摘 要： | 本文合成了聚醚型非离子性的缔合性增稠剂AT—04、AT—06和AT—10,其数均分子量分别为1.85×10~4、2.4×10~4和3.8×10~4,平均接枝数约等于4,具有星型的分子结构。其水溶液的流变性研究表明,在实验的浓度范围内,较低的剪切速率区,体系呈现牛顿流体的性质;在较高的剪切速率下,体系呈现假塑性流体特性。当浓度大于3.0％时,体系粘度突然增加,说明在该体系中,增稠剂分子间存在相互缔合。 同时实验研究了增稠剂对丙烯酸酯乳液流变性的影响,与羟乙基纤维素增稠剂比较,在相近用量下,缔合性增稠剂具有更好的增稠效应,并呈现出不同的流变性质。

| Abstract: | : The associative thickeners are synthesised by introducing hydrophobic groups into the poly-oxyethylene backbone,and the rheologic properties of their aqueous solutions in the concentration range from 3. 0 to 10. 0 % wt. are investigated. The rheologic determination of the acrylic latex containing thickeners shows that,in comparison with the cellulosic latex ones,the associative thickeners obtained exhibit higher efficiency of thickening and different rheologic Performances. |
