摘　　要：丙烯腈(AN)-丙烯酰氧乙基三甲基氯化铵(DAC)共聚物具有良好的吸湿性,与聚芳砜酰胺(PSA)共混后,可以形成均相的高分子合金。通过改变共混物两组分的质量比,分析回潮率随时间的变化规律,可以推算共混物的回潮率符合混纺织物回潮率的计算公式,而实际回潮率与理论值的偏离随时间的延长而逐渐减小。Acrylonitrile(AN)-acryloxyethyltrimethyl ammonium chloride(DAC)copolymer has good hygroscopicity.When it is blended with polyarylsulfonamide,a homogeneous polymer alloy can be formed.By changing the mass ratio of the two components of the blend and analyzing the change rule of the moisture regain with time,it can be calculated that the moisture regain of the blend conforms to the calculation formula of the moisture regain of the blended fabric,and the deviation between the actual moisture regain and the theoretical value decreases with the extension of time.
