摘要:
A fiber comprises a composition including a poly(phenylene ether). The poly(phenylene ether) has less than or equal to 240 parts per million by weight of hydroxyl groups associated with ethylene bridge groups and less than or equal to 800 parts per million by weight of hydroxyl groups associated with rearranged backbone groups, both amounts based on the weight of the poly(phenylene ether). A method of spinning a fiber from the poly(phenylene ether) is disclosed. The fiber can be spun at a low denier.
摘要:
[PROBLEMS] To provide a novel hydrophilized separation membrane for use in the treatment of a liquid, which comprises an aromatic ether polymer, is less likely to be degraded by sterilization with a high energy ray and has a controlled pore size and a high water permeability. [MEANS FOR SOLVING PROBLEMS] A porous separation membrane for use in the treatment of a liquid which is produced by a wet film formation process using an aromatic ether polymer and a hydrophilizing agent. The separation membrane can be used for medical purposes or in a pharmaceutical or food.
摘要:
Cross-linked fibers include first and second precursors, each possessing a core and at least one functional group known to have click reactivity when exposed to UV radiation. Mixtures of the first and second precursors are extruded to produce a filament and irradiated with UV light during the extrusion process.

摘要:
Fibers comprising one or more thermoplastic hydroxy-functionalized polyethers or polyesters, prepared by the reaction of a dinucleophilic monomer with a diglycidyl ether, a diglycidyl ester or epihalohydrin and, optionally a polymer which is not a hydroxy-functionalized polyether or polyester, including polyolefin, polyester, polyamide, polysaccharide, modified polysaccharide or naturally-occurring fiber or particulate filler; thermoplastic polyurethane, thermoplastic elastomer or glycol-modified copolyester.
