1 ml of 3-isocyanatopropyltriethoxysilane and 50 mg of triethylamine are added to 0.9 g of 8-cyclohexadecen-1-ol, prepared by reduction of 8-cyclohexadecen-1-one using NaBH4 in ethanol, and the mixture is kept at 80° C. for 24 hours. Low-boiling components are removed at 90° C./0.1 mbar. The residue solidifies on cooling to form a wax and shows only traces of an isocyanate band in the IR spectrum, but instead a strong band (1700 cm-1) of the ##STR5## 5.2(m, 2H, --CH=CH--); 0.6 (m, --CH2Si).
