    摘要： The invention relates to a method for producing functionalized polyoxymethylene block copolymers comprising the step of polymerizing formaldehyde in a reaction vessel in the presence of a catalyst, the polymerization of formaldehyde in addition taking place in the presence of a starter compound comprising at least 2 Zerewitinoff active H atoms, to obtain an intermediate product. The intermediate product obtained is subsequently reacted with a cyclic carboxylic acid ester or carbonic acid ester, thus obtaining a functionalized polyoxymethylene block copolymer. The invention further relates to functionalized polyoxymethylene block copolymers obtained by such a method and to the use of said copolymers.

    摘要： Perfluoropolyether carboxylic acid fluoride having the following general formula :

            F(CF 2 CF 2 CF 2 O)nCF 2 CF 2 COF

    (n : 2-200, preferably 35-70)
    can be produced by starting fluorination reaction of polyfluoropolyether carboxylic acid having the general formula as a tetrafluorooxetane polymer :

            F(CH 2 CF 2 CF 2 O)nCH 3 CF 2 COF

    (n: 2-200)
    in a dispersed state in a perfluoropolyether-based solvent with a fluorine gas at 50 ° -80 °C, then slowly elevating the fluorination reaction temperature, and finally completing the fluorination reaction at 100° - 120°C, where even in the case of fluorination reaction of the starting material with a high degree of polymerization the desired product can be produced in high yield, while suppressing the decomposition and keeping the high degree of polymerization substantially.
