New polymeric nonionic surfactans consisting of a poly(Nacetylimino)ethylene as a hydrophilic block and a perfluoroheptyl group (type A) or a poly(N-perfluoroalkanoylethylenimine) chain (type B) as a hydrophobic one were prepared and thier surface activity as well as thier surface modified ability for common polymers were investigated. The type A polymer was prepared by the cationic ring-opening polymerization of 2-methyl-2-oxazoline (MeOZO) initiated by 1 : 1 adducts of 2-perfluoroalkyl-2-oxazoline with methyl sulfonates. The type B block copolymer was synthesized by the 1 pot 2 stages copolymetrization of 2perfuluoroalkyl substituted cyclic imino ethers with MeOZO.All of the resulting surfactants were readily soluble in water and their aqueous solutions showed excellent surface tensions ( the best value was 12.8 dyn/cm) and quite low critical micelle concentrations, 0.2-2x10^4 mol/L for the type A and 0.1-1x10^4 mol/L for the type B.Moreover, the type B copolymer was applied to a new … More blending surface modifier for poly(vinyl chloride). Blend films of PVC containing various amount (0.25-5 wt%) of the block copolymer were preepared by the solvent cast method, and their surface energies were evaluated by contact angles against water as well as methylene iodide. The blend films showed an excellent water and oil repellency. For example, with 0.25 wt% of the block copolymer derived from 2-perfluotopropyl2-oxazoline and 2-methyl-2-oxazoline, contact angles of the sample were 96゜ (for H_2O) and 72゜ (for CH_2I_2).The surface modification of PVC and Nylon 6 were more conveniently achieved by the simple coating of the copolywer solution on sample sheets and the following annealing. Contact angles of the resulting PVC sheets were much the same as those prepared by the solvent cast method. The tepellent property of the samples were permanent, since contact angles against the above two liquids after five washing cycles (in water, at 50゜C, for 1 hr, and then, in hexane, at r. t., for 24 hr) were similar to the corresponding values before the washing.

制备了由聚（N乙酰亚氨基）乙烯作为亲水嵌段和全氟庚基（A型）或聚（N-全氟烷酰基乙烯亚胺）链（B型）作为疏水嵌段组成的新型聚合物非离子表面活性剂，其表面活性以及研究了普通聚合物的表面改性能力，通过阳离子开环聚合制备了A型聚合物。由2-全氟烷基-2-恶唑啉与磺酸甲酯1:1加成引发的2-甲基-2-恶唑啉(MeOZO)通过2-全氟烷基取代的环状亚氨基醚与MeOZO的1锅2阶段共聚合成B型嵌段共聚物。所有所得的表面活性剂均易溶于水，并且它们的水溶液表现出优异的表面张力（最佳值为12.8 dyn/cm）和相当低的临界胶束浓度，A型为0.2-2x10^4 mol/L，B型为0.1-1x10^4 mol/L。 ，B 型共聚物应用于含有不同含量的聚氯乙烯共混薄膜的新型共混表面改性剂。通过溶剂浇铸法制备(0.25-5wt％)的嵌段共聚物，并通过对水以及二碘甲烷的接触角来评估它们的表面能。 0.25重量％的衍生自2-全氟丙基2-恶唑啉和2-甲基-2-恶唑啉的嵌段共聚物的接触角样品的分子量为96゜（对于H_2O）和72゜（对于CH_2I_2）。通过在样品片上简单地涂覆共聚溶液以及随后对所得PVC进行接触角的退火，可以更方便地实现PVC和尼龙6的表面改性。片材与溶剂浇铸法制备的片材大致相同，因为在五次洗涤循环后与上述两种液体的接触角，样品的防水性能是永久性的。 （在水中，50゜C，1小时，然后，在己烷中，室温，24小时）与洗涤前的相应值相似。
