摘　　要：研究了脂肪酸聚氧乙烯醚的衍生物(LS1)与苯乙烯丙烯酰胺丙烯酸酯共聚物(HS1)复配体系的表面张力和对松香类物质的乳化能力。结果表明,LS1/HS1复配体系在质量比为3∶4后,表面张力以及产生最低表面张力的浓度都明显降低,发泡性趋于稳定,所制备的中性松香分散胶的机械稳定性和在中性条件下的施胶性最大,表明此时体系组分可产生较强的协同效应。Surface tension and emulsifing properties of the mixtures of styrene-acrylamide-acrylic ester copolymer (HS-1) and the derivatives of alkylalcohol polyoxyethylene ether (LS-1) were investigated. The results showed that the mixtures of LS-1 and HS-1 exhibited strong synergism at molar ratios of 4:3 - 5:2. Both the surface tension of the mixtures and its concentration in which there was the minimum surface tension decreased dramatically at that molar ratios. The neutral rosin emulsions could be prepared by using the mixtures as surfactant and showed very good sizing efficiency under neutral paper-making conditions.
