聚氨甲酰基磺酸钠表面活性的研究

聚氨甲酰基磺酸钠（ＰＣＳ）属阴离子型高分子表面活性剂。由脱环法测得其ｃｍｃ为９．１１×１０－４ｍｏｌ／Ｌ，γｃｍｃ为４６ｍＮ／ｍ；由电导法测得ｃｍｃ为８．９９×１０－４ｍｏｌ／Ｌ。ＰＣＳ对羊毛纤维有一定的渗透作用，渗透力与溶液ｐＨ值和温度基本无关。ＰＣＳ与磷酸三丁酯复配后，渗透性增强，具有增效作用。

Poly(carbamoyl sulfonate )sodium(PCS) is an anionic ploymer surfactant. Its cmc measured by detachment or conductance method is 9.11×10- 4 or 8.99×10-4 mol/ L respectirely, and its γcmc is 46 mN/m by detachment method. Penetrant test shows that PCS has penetration for wool, and its penetration power is almost independent of temperature and pH value of its solution. The penetration power is enhanced when PCS is mixed with tributyl phosphate.
