A new bis(perfluorocyclohexane carbonyl) peroxide was prepared by the reaction of the corresponding acyl fluoride and hydrogen peroxide. This peroxide was applicable for the direct introduction of perfluorocyclohexyl group into various organic molecules such as acrylic acid oligomer, benzene and polystyrene; in particular interest, not only equatorial but also axial conformational isomers were isolated in phenylperfluorocyclohexane thus obtained.

The invention relates to a preparation method of perfluorodiacyl peroxide. The preparation method specifically includes: enabling an adduct of perfluoroacyl halide, weak base and hydrogen peroxide toreact in an inert solvent so as to obtain the perfluorodiacyl peroxide. The perfluorodiacyl peroxide is widely utilized as an initiator in free radical polymerization reaction. The preparation methodof the perfluorodiacyl peroxide is high in safety performance, simple to operate, high in yield and capable of preparing high-purity perfluorodiacyl peroxide.

Disclosed herein are a novel perfluoroalkyl vinyl ether compound, a process for preparing a copolymer by using the perfluoroalkyl vinyl ether compound, and an optical plastic material comprising a copolymer prepared by the process. More specifically, the perfluoroalkyl vinyl ether has a particular molecular structure; the process is performed by copolymerizing the perfluoroalkyl vinyl ether compound with a common fluorinated olefin in the presence of a perfluorinated radical initiator; and, the optical plastic material comprises a copolymer prepared by the process and optionally a dopant. The copolymerization of the perfluoroalkyl vinyl ether with a common fluorinated olefin can provide a copolymer having a high molecular weight. In addition, appropriate control of the composition of the monomers can provide a completely amorphous copolymer. Since the polymer prepared by the process exhibits excellent thermal properties and is substantially transparent in the UV and near IR regions, it can be usefully applied to various optical plastic materials. Furthermore, a preform for a GI type plastic optical fiber fabricated by using the copolymer and the dopant has a high Tg, thus being stable, and a parabolic refractive index profile due to the presence of the dopant.
