    • The invention relates to a thermoplastic polyurethane comprising the following structural unit: R2—CO—NH—R—Si(R1)3-x(OR1)x where: R is an aliphatic, araliphatic, or aromatic organic radical having from 1 to 20 hydrocarbon atoms, R1 is an alkyl radical or aryl radical having from 1 to 10 carbon atoms, R2 is —NR3—CO—R4 or —O—R5—O—, R3 is a section of the polymer chain of the thermoplastic polyurethane, in particular a radical which derives from the diisocyanate used to prepare the thermoplastic polyurethane, R4 is a section of the polymer chain of the thermoplastic polyurethane, in particular a radical which derives from the following compounds used to prepare the thermoplastic polyurethane: compounds (b) reactive toward isocyanates, or from the chain extender (c), R5 is an alkylene radical having from 2 to 8 carbon atoms, preferably from 3 to 6 carbon atoms, and x is 1, 2 or 3.
    • 本发明涉及一种包含以下结构单元的热塑性聚氨酯:<?in-line-formula description =“In-line formula”end =“lead”→> R 2 -CO-NH-R -Si(R 1 1)3-x X(或1个)x 直线公式描述 其中:R是具有1至20个烃基的脂族,芳脂族或芳族有机基团,R 1是烷基或芳基 具有1至10个碳原子的基团R 2是-NR 3 -CO-R 4或-OR 5, SUB> -O-,R 3 3是热塑性聚氨酯的聚合物链的一部分,特别是衍生自用于制备热塑性聚氨酯的二异氰酸酯的基团R 4, SUB>是热塑性聚氨酯的聚合物链的一部分,特别是衍生自以下用于制备热塑性聚氨酯的化合物的基团:化合物(b)对异氰酸酯反应,o r为扩链剂(c),R 5为具有2至8个碳原子,优选3至6个碳原子的亚烷基,x为1,2或3。
