Alternatively, the polyfluoro-1-alkene is produced by reacting the polyfluoroalkyl iodide [II] with a nitrogen-containing organic basic compound, and is obtained product [I] as one fraction thereof. By the copolymerization of the polyfluoro-1-alkene with other fluorinated olefin monomers, a fluorine-containing copolymer having excellent light transmittance in the visible light range is formed.
The present invention relates to active delivery system formulations, and methods of making and using the same. Said formulations, when applied to a substrate surface, form a protective coating on the surface and permit constituent active agents to act on the surface and in the surrounding medium.

Is disclosed a cycloaliphatic polyepoxy compound represented by following Formula (1):
wherein Y represents a linkage group or a single bond; and HAS each represent hydrogen atom at the junction between cyclohexane ring and oxirane ring, and the cyclohexane rings may each further have one or more substituents in addition to the groups shown in the formula. The cycloaliphatic polyepoxy compound contains stereoisomers in such proportions as to have a ratio A/B of 1.8 or more, wherein "A" and "B" are integrated intensities of signals of protons at the junction between cyclohexane ring and oxirane ring as determined by 1H-NMR spectroscopy of the compound, in which "A" represents the integrated intensity of a signal observed at a lower magnetic field, and "B" represents the integrated intensity of a signal observed at a higher magnetic field.
