  O Water-absorbent, starch copolymerisates which comprise a non-linear lattice of starch chains linked together by polymeric linkages represented by the formula wherein Starch represents a starch chain of D-glucose units, Z represents an organo group which links the group to the carbon atom of the starch chain by a sulphur or an oxygen atom, R is hydrogen or a monovalent organic radical, M represents a plurality of copolymerised ethylenically unsaturated monomers with "p" representing the number of copolymerised monomeric units in the linkage, (W) is a water-attractant group linked to the polymeric linkage and "n" represents the number of (W) moieties contained within the polymeric linkage of the copolymerised monomers with the number of (W) moieties being sufficient to impart water-absorbency properties to the copolymerisate. The water-absorbent starch copolymerisate may be easily prepared into a desired configuration for a particular end-use or combined with other substrates or carriers. The unpolymerised starch and monomers or precursors thereof may be applied or incorporated into a suitable carrier.or substrate and copolymerised in situ to provide a composite article of unitary construction with the water-absorbent starch copolymerisate permanently bonded or affixed thereto.

  O 具有吸水性的淀粉共聚物，它由通过聚合物链节连接在一起的淀粉链的非线性晶格组成，聚合物链节由以下式子表示 其中，淀粉代表由 D-葡萄糖单元组成的淀粉链，Z 代表有机基团，它将有机基团与淀粉链的碳原子连接在一起。 R 是氢或一价有机基，M 代表多种共聚乙烯不饱和单体，"p "代表连接中共聚单体单元的数量、(W）是与聚合连接相连的吸水基团，"n "代表共聚单体的聚合连接中包含的（W）分子的数量，（W）分子的数量足以使共聚物具有吸水性能。吸水性淀粉共聚物可以很容易地制备成特定最终用途所需的结构，或与其他基质或载体结合。可将未聚合的淀粉及其单体或前体涂抹或掺入适当的载体或基质中，并在原位进行共聚，以提供具有吸水性淀粉共聚物永久粘合或附着于其上的整体结构的复合物品。

  The invention provides an improved cellulosic ester or ether product with an ester or ether degree of substitution (D.S.) of between 2.0 and about 2.9 which is derivatized or further reacted by reaction with an acrylamide reagent to substitute to a pendent acrylamide functionality D.S. of from about 0.05 to about 0.5 (leaving an unreacted or unsubstituted hydroxyl D.S. of from about 0.05 to about 0.95), and to thereby provide a polymerizable organic solvent-soluble product which is insoluble in water and copolymerizable with vinyl monomers. The product is prepared by reacting a cellulose ester or ether derivative with a catalyst and the acrylamide reagent at a pH of from about 4.2 to about 4.5. The reaction is carried out at a temperature between 80°C and 120°C for from one-half to three hours, while removing the water of reaction.

  本发明提供了一种改进的纤维素酯或醚产品，其酯或醚的取代度（D.S.）在 2.0 至 2.9 之间，通过与丙烯酰胺试剂反应进行衍生化或进一步反应，以取代为悬垂的丙烯酰胺官能团，D.S.在约 0.05 至约 0.5 之间（留下未反应或未取代的羟基，D.S.在约 0.05 至约 0.95 之间），从而提供聚合物。S.约为 0.05 至约 0.5（留下未反应或未取代的羟基 D.S.约为 0.05 至约 0.95），从而提供一种不溶于水且可与乙烯基单体共聚的可聚合有机溶剂溶性产品。该产品的制备方法是将纤维素酯或醚衍生物与催化剂和丙烯酰胺试剂在 pH 值约为 4.2 至 4.5 的条件下进行反应。反应在 80°C 至 120°C 的温度下进行半小时至三小时，同时除去反应水。
