Patent number: 6106745Abstract: Disclosed is a method of making a graded index polymer optical fiber comprising a multicomponent spinning process employing spinning masses comprising a core spinning mass and a sheath spinning mass, the spinning masses comprising a polymer, a polymerizable monomer, and an initiator. The monomer in the core spinning mass has a higher refractive index than the monomer in the sheath spinning mass, and the spinning masses are extruded and cured. The spinning conditions are chosen such that the monomers are substantially contained within the fiber during extrusion and curing and the total of the spinning masses is intrinsically thread forming. The spinning masses may be extruded in, e.g., water. The core and the sheath polymer may be, e.g., poly(methyl methacrylate); the core monomer may be methyl methacrylate, and the sheath monomer may be 2,2,3,3-tetrafluoropropyl methacrylate; or the core and the sheath polymer may be, e.g.Type: GrantFiled: May 13, 1998Date of Patent: August 22, 2000Assignee: Akzo Nobel NVInventors: Bastiaan Krins, Richard Hendrikus Gerrit Brinkhuis

Patent number: 5194210Abstract: Fibers of an alternating carbon monoxide-ethylene polymer having a molecular weight of at least 100,000 g/mole and a birefringence of at least 650.times.10.sup.-4 can be formed by first extruding a solution of the polymer in a mixed solvent system comprising an aromatic alcohol which is free of alkyl substituents on the aromatic nucleus and another solvent which is a liquid and is other than an aromatic alcohol. The extrusion into the solvent is at an extrusion rate of at least 1 m/min and forms a solvent-containing article which is then cooled or coagulated in a non-solvent for the polymer. The solvent is removed by extraction with a non-solvent for the polymer which is soluble in the mixture of solvents and the resulting article is drawn at a temperature of at least 180.degree.
