Abstract

1492040 Articles comprising cellulosic particles HOECHST AG 20 Dec 1974 [24 Dec 1973] 55196/74 Heading C3F [Also in Division B5] Cellulose ethers, inherently water-soluble but rendered at least partly water-insoluble, but still water-absorbent by cross-linking or other chemical modification, are uniformly distributed in, or over a surface of, a shaped article composed of a film- or fibre-forming polymer which is insoluble in water. The cellulose ether may be carboxymethyl-, hydroxyethyl-, or methylhydroxyethyl-cellulose and is preferably in the form of particles of a size within the range of from 0À01 to 2 mm. Several modifying agents are used, epichlorohydrin most commonly. The shaped articles in the examples are films of hydrated cellulose (from viscose), cellulose acetate and hydroxyethyl cellulose and fibres of polyethylene.
