摘　　要：测定了3-十二烷氧基-2-羟丙基三甲基溴化铵(C12TAB)在PVP、PEG和溴化钠存在下的泡沫性能。结果表明:含量相同时,C12TAB/NaBr混合体系的起泡性能高于C12TAB/高分子体系,而稳泡性能低于后者。含量相同的C12TAB/高分子体系,PVP对C12TAB的影响好于PEG。The foaming properties of 3-dodecylalkoxyl-2-hydroxypropyl trimethyl ammonium bromide (C_(12)TAB)were determined at the presence of salt NaBr and polymers PVP and PEG.The experimental results showed that with same ratio of ingredients in the blending system,the foaming capability of the blending system of C_(12)TAB/NaBr is higher than the blending systems of the C_(12)TAB/PEG and C_(12)TAB/PVP,while the foam stability is weaker than that of the latters.The influence of PVP on the foaming properties of the system is higher than that of PEG at the same concentration.
