An improved process for extruding plastic optical fiber without the need to prepare a preform is provided. Specifically, it was discovered that conventional extrusion techniques, e. g. , screw extruders, tended to introduce an undesirable amount of particulate contaminants which increased the loss of the drawn fiber. To overcome this problem, the invention substantially reduces the number of mechanical interactions that contribute to such contamination. The process of the invention does so by using fluid pressure, instead of, e. g. , screw extruders, to induce polymer flow. The process also controls the flow characteristics of the polymer, or halts the flow altogether, without mechanical controls. Specifically, the temperature of the sections through which the polymer flows is controllably adjusted, such that it is possible to bring the polymer to a desired flow rate or even to a solid state to provide a plug.

The invention relates to plastic optical fiber (POF) processes and systems and involves improved non-polishing termination techniques. The techniques provide good physical and optical characteristics, i. e. , smoothness, at the termination point, thereby providing lower losses than conventionally obtained. According to one embodiment, POF is cut while the fiber is under compression. According to another embodiment, the POF is notched and then pulled at a relatively high strain rate to induce fracture. The rate is such that the strain remains in the elastic region, i. e. , the fiber exhibits brittle, as opposed to ductile, behavior during the strain. The brittle behavior provides a smooth termination surface, as opposed to a plastically-deformed surface.

We have determined that unlike the most multimode silica fiber, multimode polymer fiber often exhibits a delay characteristic that has a broad low dispersion region where propagation delay of spatially restricted optical pulses remains relatively constant. This low dispersion region is centered around the center axis of the fiber core as a function of launch position. By directing a transmitted optical pulse to this region, we have determined that optical pulse dispersion can be significantly reduced without the need for using the prior art technique of using a single mode fiber spliced in series with the multimode fiber to reduce dispersion. A polymer fiber based optical transmission system using this arrangement exhibits relaxed alignment tolerances between the optical source and polymer fiber, while reducing dispersion and increasing bandwidth-length product.

Described herein are articles for separating gases. The article includes an amorphous fluorinated copolymer containing, one or more types of fluorinated dioxolane ring monomers, and one or more types of fluorinated non-dioxolane ring monomers, optionally with crosslinking between the fluorinated copolymer chains. The copolymers of fluorinated dioxolane ring monomers and fluorinated non-dioxolane ring monomers show a large differential in the permeability of certain gases compared with other gases. The resulting polymer membranes have superior selectivity and reliability performance in certain gas separations compared with previous compositions known to the art. Methods for making and using the article described are also provided,

Described herein are amorphous fluorinated copolymers produced by the polymerization of one or more fluorinated ring monomers and one or more fluorinated comonomers containing multiple ether oxygens. The copolymers are suitable in many high-technology applications, such as optical fibers, anti-reflection coatings, protective coatings, and gas separation membranes. In one aspect, the copolymers are useful is in the field of membrane-based gas separation processes. In one aspect, amorphous copolymer is produced by polymerizing (a) one or more fluorinated ring monomers in the amount of 1 mol % to 99.5 mol %, wherein the fluorinated ring monomer is at least a five membered ring and (b) a comonomer in the amount of from 0.5 mol % to 99 mol %, wherein the comonomer comprises a fluorinated compound with two or more ether oxygens.

Described herein are articles for separating gases. The article includes a selective layer consisting of a crosslinked amorphous fluorinated copolymer containing one or more types of fluorinated ring monomers, with crosslinking between the fluorinated copolymer chains. The crosslinking improves the mechanical properties of the fluoropolymer, thereby permitting use of polymer types which would otherwise be excessively brittle. The resulting crosslinked polymer membranes have superior selectivity and reliability performance compared with previous compositions known to the art. Methods for making and using the article described are also provided.
