    • PURPOSE: Provided are novel diols containing a perfluoroalkyl group or perfluoroalkenyl group, which is commonly abbreviated as an "Rf group", and also polyurethanes using the diols. CONSTITUTION: Fluorine-containing diols is represented by (I), wherein Rf represents a perfluoroalkyl or perfluoroalkenyl group having 1 to 20 carbon atoms; X represents a substituted or unsubstituted alkylene group having 1 to 10 carbon atoms, a substituted or unsubstituted alkenylene group represented by -CH=CH-(CH2)n- in which n stands for an integer of from 1 to 10, or in which n stands for an integer of from 0 to 6; Y represents a direct bond, -O-, -NH-, or -R0-NH- in which R0 is an alkylene group having 1 to 6 carbon atoms; Z represents a direct bond or -N(R')R- in which R is an alkylene group having 1 to 20 carbon atoms and R' is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; R1 and R2 each independently represent a divalent organic group; and R3 represents a residual group of an aliphatic, alicyclic or aromatic diisocyanate. These fluorine-containing diols are useful for the production of polyurethanes.
    • 目的:提供通常缩写为“Rf基”的全氟烷基或全氟烯基的新型二醇,以及使用二醇的聚氨酯。 构成:含氟二醇由(I)表示,其中Rf表示碳原子数1〜20的全氟烷基或全氟链烯基; X表示取代或未取代的碳原子数1〜10的亚烷基,取代或未取代的由-CH = CH-(CH 2)n表示的亚烯基,n表示1〜10的整数,n表示n 代表0到6的整数; Y表示直接键合,-O - , - NH-或-RO-NH-,其中R 0是具有1至6个碳原子的亚烷基; Z表示直接键或-N(R')R-,其中R是具有1至20个碳原子的亚烷基,R'是氢原子或具有1至6个碳原子的烷基; R1和R2各自独立地表示二价有机基团; 并且R 3表示脂族,脂环族或芳族二异氰酸酯的残基。 这些含氟二醇可用于生产聚氨酯。
