摘要: A process is disclosed for extruding fibers from ionomer resins that are not blended with polyolefins, monomers, solvents, or other conventional compounds typically used in connection with processing fibers that contain ionomers. The preferred ionomers are 90% neutralized metal salts of copolymers of from at least about 60 to 90% ethylene and from at least about 10 to 40% acrylic acid. Multivalent metal cations can be used to introduce cross linking for control of the solubility and swellability of the fibers. The fibers and webs produced therefrom can be produced by meltblowing and can be used to provide a less expensive alternative to superabsorbent powders.

摘要: Surfactants of a defined formula, typically prepared by reacting an alkoxylated hexitol fatty acid ester with a di- or tri-basic acid to induce a low degree of polymerization. The surfactants exhibit a higher viscosity in aqueous solution and in admixture with other conventional surfactants than the unpolymerized material.
