ABSTRACT:
An insoluble etherified cellulose graft copolymer is provided comprising etherified cellulose which is soluble in water in the absence of grafting and is chosen from the group consisting of the alkali metal salts of carboxyalkyl cellulose, sulfoalkyl cellulose and phosphonoalkyl cellulose. The etherified cellulose has grafted onto its cellulose backbone side chains of polymer moieties in sufficient quantities to render the grafted etherified cellulose insoluble. The products of this invention are used alone or mixed with other absorbent materials such as unmodified cellulose, in the manufacture of absorbent napkins, tampons, sponges and the like.
