    • This invention relates to a process for coating the surface of a shaped article of cellulose hydrate with a layer of polymer material which comprises applying to the surface of a shaped article in the gel state and based on cellulose hydrate, a liquid layer of an aqueous solution of a chemically modified protein obtained by mixing an aqueous alkaline protein solution with an aqueous solution of N-methylol-acrylamide or N-methylol-methacrylamide or of the alkoxy derivatives thereof of aliphatic alcohols with 1 to 8 carbon atoms, particularly of organic, tetrafunctional, doubly unsaturated compounds of the general formula ##STR1## in which R.sub.1 and R.sub.2 are hydrogen or an alkyl group with 1 to 6 carbon atoms, and R.sub.3 is the group --(CH.sub.2).sub.n --, n being an integer from 1 to 8, or the group ##STR2## in which R.sub.4 is an alkyl group with 1 to 18 carbon atoms, SUBJECTING THE LIQUID MIXTURE TO A DWELL TIME, HEATING THE COATED SHAPED ARTICLE, AND WETTING THE SHAPED ARTICLE. The invention also relates to a shaped article of cellulose hydrate having a coating of protein thereon.
    • 本发明涉及一种用聚合物材料层涂覆纤维素水合物的成型制品的表面的方法,该方法包括以凝胶状态施加到成形制品的表面上,并且基于纤维素水合物,水溶液的液体层 通过将碱性水溶液与N-羟甲基 - 丙烯酰胺或N-羟甲基 - 甲基丙烯酰胺的水溶液或其具有1-8个碳原子的脂族醇的烷氧基衍生物混合而获得的化学修饰的蛋白质,特别是有机,四官能 ,其中R 1和R 2为氢或具有1至6个碳原子的烷基的通式为“IMAGE”的双不饱和化合物,R 3为基团 - (CH 2)n - ,n为1至8的整数, 或其中R 4为具有1至18个碳原子的烷基的基团,将液体混合物置于干燥时间,加热涂覆的形状和润湿形状的物品。 本发明还涉及在其上具有蛋白质涂层的水合物的成形制品。
