Title:
【発明の名称】ペルオキシ酸素のない及びペルフルオロエポキシ基をペルフルオロポリエ-テル鎖に沿つて位置させて含有するペルフルオロポリエ-テル及びそれらの誘導体
Document Type and Number:
Japanese Patent JPH0822911
Kind Code:
B2
Abstract:
Perfluoropolyethers having fluorinated epoxy groups positioned along their perfluoropolyether chain, and free from peroxidic oxygen, are obtained by means of a low-temperature oxidation process, in the liquid phase, with molecular oxygen and in the presence of U.V. light, of a mixture of a perfluorinated monoolefin and a perfluorinated conjugated diene, and by the subsequent photochemical decomposition of the peroxy groups contained in the photooxidation product, carried out by treating the peroxy-groups containing product with U.V. light at a temperature of from 0 DEG C to 160 DEG C. Derivatives of said epoxy containing perfluoropolyethers in which the epoxy groups have been converted to functional groups are also disclosed.
