Metal surfaces, metal-oxide surfaces, metal-salt surfaces, silicon-comprising surfaces and/or high-molecular-weight aquoxide-comprising organic surfaces are coated. The coating is carried out with a reagent having a reactive group chosen from Si&mdash;H, Sn&mdash;H, and Ge&mdash;H. The reagent is applied in liquid, pasty, or solid form to the surface that is to be coated. Furthermore, the coating reaction requires the presence of an activator. A platinum metal in form of a compound or in metallic form is used as activator.

The biocompatible multi-block copolymer is obtainable by linear polycondensation of at least two .alpha.,.omega.-dihydroxypolyesters acid and/or .alpha.,.omega.-dihydroxypolyethers with a diisocyanate, diacid halide or phosgene. The block copolymer is preferably degradable in the human or animal body. The block copolymer is suitable for the production of medical implants and surgical aids.
