摘　　要：利用弹性光散射(ELS)研究阴离子表面活性剂十二烷基苯磺酸钠(SDBS)对水溶液中P(NIPAM-co-NVP)共聚物分子链聚集的影响。通过对比光强度的变化,来检测SDBS产生的作用。分析得出添加SDBS后最大散射波长位于共聚物和SDBS的最大散射波长之间,且分子链聚集和解聚的温度都升高,而达到平衡后的最大散射强度降低。这些现象的出现说明SDBS与共聚物发生作用,影响共聚物分子链的聚集行为。SDBS to the aggregation of P（NIPAM-co-NVP） copolymer chain in aqueous solution was investigated with elastic light scattering （ELS）. The effect of SDBS can be detected by contrast the changes of ELS scattering intensity. After analysis we get that the maximum scattering wavelength after adding SDBS is between the copolymer and SDBS only, and the temperature of aggregation and dissociation becomes higher while maximum scattering intensity to the balance is lower. The appearances prove that SDBS and copolymer have an effect, and SDBS can impact the aggregation ofP （NIPAM-co-NVP） copolymer chain.
