The interaction of polyvinylpyrrolidone (PVP) with an anionic surfactant (sodium dodecyl sulfate, SDS), a nonionic surfactant (pentaethylene glycol monodecyl ether, C(10)E(5)), and a zwitterionic surfactant (lauryl amido propyl betaine, LAPB) has been investigated by means of pulsed gradient spin-echo NMR (FT-PGSE NMR), allowing self-diffusion coefficients to be determined. The results confirm the strong interaction prevailing in the PVP/SDS system, whereas no association has been observed in the PVP/C(10)E(5) and PVP/LAPB systems. Mixing PVP with two surfactants, namely SDS and C(10)E(5) or SDS and LAPB, results in the formation of ternary aggregates between the polymer and the mixed micelles. Copyright 2001 Academic Press.
通过脉冲梯度自旋回波核磁共振（FT-PGSE NMR）研究了聚乙烯吡咯烷酮（PVP）与阴离子表面活性剂（十二烷基硫酸钠，SDS）、非离子表面活性剂（五乙二醇单癸醚，C(10)E(5)）和两性离子表面活性剂（月桂酰胺丙基甜菜碱，LAPB）之间的相互作用，从而确定了自扩散系数。结果证实了PVP/SDS体系中存在强烈的相互作用，而在PVP/C(10)E(5)和PVP/LAPB体系中未观察到缔合现象。将PVP与两种表面活性剂（即SDS和C(10)E(5)或SDS和LAPB）混合，会导致聚合物与混合胶束之间形成三元聚集体。版权所有2001年学术出版社。
