    • The present invention relates to a novel method of preparing films based on cross-linked poly(ethylene oxide). This method comprises the steps consisting in: a) dissolving said polymer or copolymer of ethylene oxide, alone or in a mixture, with a water-soluble polymer, in a solvent system made up of water, an organic solvent, or a mixture in any proportion. of water and of organic solvent, in the presence of an effective amount of a photo-initiating agent or of a cross-linking agent; b1) either drying the solution thus obtained until the solvent system has evaporated, when this solvent system is made up exclusively of an organic solvent, to thus obtain a dry film, and treating the film thus obtained under conditions enabling an amount of water to be absorbed of between 10 and 100% by weight with respect to the weight of the polymer; b2) or drying the solution thus obtained until the solvent system has evaporated, when this solvent system is made up of water or a water-organic solvent mixture, to thus obtain a film containing between 10 and 100% by weight of water with respect to the weight of the polymer; c) irradiating the film thus obtained by means of ultraviolet rays of a wavelength of between 200 and 400 nm, for a period of time sufficient to enable the cross-linking.
    • 本发明涉及一种基于交联聚(环氧乙烷)制备薄膜的新方法。 该方法包括以下步骤:a)将单独或混合物中的环氧乙烷的聚合物或共聚物与水溶性聚合物溶解在由水,有机溶剂或任何混合物中混合的溶剂体系中 比例。 的水和有机溶剂,在有效量的光引发剂或交联剂的存在下; b1)干燥所得到的溶液直到溶剂体系蒸发,当该溶剂体系仅由有机溶剂组成时,从而得到干膜,并且在使得一定量的水的条件下处理由此获得的膜 相对于聚合物的重量吸收10至100重量%; b2)或干燥所得到的溶液直到溶剂体系蒸发,当该溶剂系统由水或水 - 有机溶剂混合物组成时,从而获得含有10至100重量%水的膜相对于 聚合物的重量; c)通过波长在200和400nm之间的紫外线照射由此获得的膜足以实现交联的时间。
