摘　　要：合成了一系列不同聚合度的聚烷基酚聚氧乙烯醚(HHL)型非离子表面活性剂。通过红外光谱,核磁共振等仪器对其结构进行表征,用表面张力法对不同聚合度的合成产物的表面性能进行研究,并对不同聚合度的表面活性剂的物理化学参数进行理论分析。结果表明:三聚烷基酚聚氧乙烯醚型非离子表面活性剂较相应单体的烷基酚聚氧乙烯醚表面活性剂,表面活性和吸附能力有较大的提升。A series of different degrees of polymerization polyalkylphenol polyoxyethylene ethers （HHL） type non-ionic surface-active agent were synthesized. By infrared spectroscopy, the nuclear magnetic resonance and other means, the characterize of the structure was obtained. The surface properties of the synthetic product with different degree of polymerization were studied by the surface tension method. The results show that compared with the corresponding monomers polyoxyethylene alkylphenol ether （HHL） non-ionic polyalkylphenol polyoxyethylene ethers （HHL） were better, which had a greater surface activity and adsorption capacity.
