摘要： A novel fluoropolymer which can be an optical resin material having a low refractive index and excellent heat resistance, and a novel fluorinated diene compound having two unsaturated bonds, capable of presenting such a fluoropolymer, are presented. Further, by virtue of the low refractive index and excellent heat resistance, the polymer presents a high performance optical transmitter and a plastic optical fiber. A fluorinated diene compound represented by CF2nullCFCF(ORf)CF2OCFnullCF2 (wherein Rf is a perfluoroalkyl group such as a trifluoromethyl group), and a fluoropolymer thereof. Further, an optical transmitter made by using such a fluoropolymer, and a plastic optical fiber having a core comprising such a fluoropolymer and a fluorinated low molecular compound contained therein as a refractive index-increasing agent.

摘要： A perfluoropolyether and a composition comprising the perfluoropolyether are provided in which the perfluoropolyether comprises at least one bromine or iodine atom at the primary position of the perfluoropolyether. Also provided is a process for producing the composition in which the process comprises contacting a perfluoropolyether acid fluoride moiety with a metal bromide or metal iodide or a suitable polyether secondary iodide under a condition sufficient to effect the production of a perfluoropolyether comprising at least one bromine or iodine at the primary position.

摘要： The present invention includes methods and compositions for increasing the fluorous nature of an organic compound by reacting it with at least one fluorous compound to produce a fluorous tagged organic compound. The increased fluorous nature of the fluorous tagged organic compound can then be utilized to separate the fluorous organic compound from untagged reagents, reactants, catalysts and/or products derived therefrom. The resultant fluorous tagged organic compound can be subjected to subsequent chemical transformations, wherein the fluorous nature of the tagged compound is utilized to increase the ease of separation of the fluorous tagged organic compound from untagged reagents, reactants, catalysts and/or products derived therefrom, after each chemical transformation. The chemical transformations result in a second fluorous tagged organic compound wherein the fluorous nature of the second fluorous tagged organic compound can then be reduced by removing the fluorous group therefrom, thereby producing a second organic compound that may be employed as a pharmaceutical compound or intermediate, or a combinatorial library component.
