Patent number: 5783608Abstract: Separation functional fibers are produced by exposing fibers with a core/sheath structure to an ionizing radiation and then grafting a polymerizable monomer to the fibers. Ion-exchange fibers are produced by introducing, through radiation-initiated graft polymerization, ion-exchange groups into the sheath of each of composite fibers the core and the sheath of which are composed of different kinds of high-polymer components. The separation functional fibers and the ion-exchange fibers are useful in various applications such as the production of pure water in electric power, nuclear, electronic and pharmaceutical industries and the demineralization of high-salt content solutions in the production of foods and chemicals. The fibers are also useful in removing harmful components from gases, as well as odorous components such as ammonia.Type: GrantFiled: February 21, 1997Date of Patent: July 21, 1998Assignees: Ebara Corporation, Japan Atomic Energy Research InstituteInventors: Takanobu Sugo, Toshihiko Yamada, Hiroyuki Shima, Kunio Fujiwara

Patent number: 5266607Abstract: Polymer compositions having a first and second portion selected from polypropylenes, polyethylenes, propylene-ethylene copolymers and mixtures thereof having enhanced crystallization properties and a method for producing the same are disclosed. Antioxidant is mixed with the first portion, 0.01 to 1.25 wt %, of the composition which is then irradiated to a dosage of 5-30 Mrads of ionizing radiation in air to induce cross linking. The irradiated first portion is then blended with the non-irradiated second portion. The cross-linked polymer is believed to provide nucleation sites for the initiation of crystallization, thereby enhancing crystallization of the polymer as evidenced by elevated DSC freeze points. Crystallization of the polyolefin is enhanced without any detrimental effects on hexane or xylene extractability of the polymer and without degrading the composition to any appreciable extent.Type: GrantFiled: June 13, 1991Date of Patent: November 30, 1993Assignee: Rexene Products CompanyInventors: Bennie M. Lucas, V. Krishnamurthy
