通过双环草内酰胺8-氧杂-6-氮杂双环[3.2.1]辛烷-7-酮的阴离子聚合制备了一种以聚酰胺为外链段、聚氧乙烯为内链段的新型嵌段共聚物。使用具有末端异氰酸酯基团的聚氧乙烯作为由聚氧乙二醇和过量的甲苯-2，4-二异氰酸酯获得的活化剂。通过将所得嵌段共聚物的氯仿-甲醇（10:1）溶液浇铸，很容易获得亲水膜。讨论了共聚物膜与水分子的相互作用与水的吸附和渗透的关系。
A new block copolymer composed of polyamide as outer segments and polyoxyethylene as an inner segment was prepared by the anionic polymerization of a bicyclic oxalactam, 8-oxa-6-azabicyclo[3.2.1]octan-7-one. A polyoxyethylene having terminal isocyanate groups was used as an activator obtained from polyoxyethylene glycol and an excess of tolylene-2,4-diisocyanate. A hydrophilic membrane was easily obtained by casting from a chloroform–methanol (10: 1) solution of the resulting block copolymer. The interaction of the copolymer membrane with water molecules was discussed in relation to the adsorption and permeation of water.
