制备功能性水溶性膜的方法
摘要：
本发明涉及一种制备水溶性膜的方法，其中该水溶性膜包含至少一个包含可通过在至少一种聚醚组分PE)存在下自由基聚合单体组合物M1)得到的聚合物组合物P1)或由其组成的层S1)，该单体组合物M1)包含至少一种选自α,β-烯属不饱和单羧酸和二羧酸、α,β-烯属不饱和单羧酸和二羧酸的盐、α,β-烯属不饱和单羧酸和二羧酸的酸酐及其混合物的单体A)，该聚醚组分PE)选自具有至少200g/mol的数均分子量的聚醚醇、该类聚醚醇的单-和二-(C1-C6烷基)醚、包含聚醚基团的表面活性剂及其混合物，其中该膜还可包含其他层且其中将该层流延于载体材料上。
摘要（英）：

The present invention relates to a method for producing water-soluble films, wherein the water-soluble film comprises at least one layer S1) containing or consisting of a polymer composition P1), obtainable by free-radical polymerization of a monomer composition M1) which contains at least one monomer A) selected from [alpha],[beta]-ethylenically unsaturated mono-and dicarboxylic acids, salts of [alpha],[beta]-ethylenically unsaturated mono-and dicarboxylic acids, anhydrides, [alpha],[beta]-ethylenically unsaturated mono-and dicarboxylic acids, and mixtures thereof, in the presence of at leastone polyether component PE), which is selected from polyetherols having a number average molecular weight of at least 200 g/mol, mono-and di-(C1-C6-alkyl) ethers of such polyetherols, polyether groups-containing surfactants and mixtures thereof, wherein the film can have further layers, and wherein the layers are cast on a support material.
