    摘要: The present invention pertains to a flexible organic polymeric optical fiber core having an adherent flexible organic polymeric cladding on the outer surface. More particularly, the invention relates to an organic polymeric optical fiber having a polysiloxane cladding for long term in vivo use in the tissue of a living mammal, preferably a human being. In addition to compatibility in live tissue and body fluids, such a fiber must be capable of repeatedly being deformed in a small bend radius without losing the ability to transmit light. The clad optical fibers are used to measure levels of components (e.g., pH, oxygen, carbon dioxide) in living, moving tissue such as the heart or lungs.

    摘要: Epoxides of the invention are those of the formula ##STR1## wherein J is H or F, the same in each occurrence; Q is a valence bond or --O--, the same in each occurrence; and Y is H or F, independently. When cured, these epoxides are superior in moisture resistance, flame retardance, and thermal stability to the corresponding non-fluorinated, prior art epoxides. The epoxides of the preceding formula may be made by first reacting an allylic halide of the formula CJ.sub.2 .dbd.CJ--CJ.sub.2 --X, wherein X is halogen, with a compound of the formula ##STR2## wherein Z is MO, hal.Mg or Ag; M is an alkali metal; and hal=Br or I; then if Y is to be F, converting the --CH group to a --CF group, and finally, oxidizing the CJ.sub.2 .dbd.CJ group to a ##STR3## group.
