摘要：Water-insoluble, water-swellable fibers adapted to bind aqueous fluids such asbody exudates are prepared by spinning fibers from an organic solvent solution of acopolymer of maleic anhydride with suitable vinyl monomers. The copolymer solutionalso contains a small amount of a polyfunctional cross-linking agent such as a glycol oralkylene diamine which reacts to cross-link the copolymer chains when the fibers areheated and dried. The cross-linked copolymer fibers are then rendered hydrophilic andwater-swellable by reaction with ammonia or an alkali metal hydroxide.
