摘　　要：通过检测聚合物在溶解过程中的电阻率变化,来描述聚合物的溶解程度。分别测定了在25℃条件下在AP-P4溶液中加入α-环糊精、β-环糊精、γ-环糊精对溶液溶解时间和溶液黏度的影响。结果表明:环糊精虽然能降低溶解时间,但是会导致溶液黏度下降,并且以环糊精与聚合物疏水基团摩尔比为4∶1或者6∶1时的β-环糊精缩短溶解时间的效果最好。By detecting the change of the resistivity of the polymer in the process of dissolution,to describe the dissolution degree of polymer.The effects of the addition ofα-cyclodextrin,β-cyclodextrin andγ-cyclodextrin on the solution time and viscosity of the polymer in AP-P4 solution at 25℃.Results show that:Although the cyclodextrins could reduce the dissolution time,but it will lead to a decrease in the viscosity of the solution,and to cyclodextrin and the hydrophobic group molar ratio is 4:1 or 6:1,andβ-cyclodextrin relationship dissolution time is the best.
