Abstract: A method for producing high-molecular weight, solid, meltable, thermoplastic, pre-ceramic polymers by converting liquid low-molecular weight polysilazanes in a solvent, in the presence of a catalyst, and a stopping reagent stopping the reaction as soon as the desired degree of polymerization is achieved. The obtained polysilazanes can be processed by conventional industrial methods, such as, for example, extrusion, injection molding, melt spinning, calendering, film and hollow body blowing, rotational molding, fluidized bed sintering, flame spraying and transfer molding (RTM and DP RTM).

Abstract: A coating for surfaces, comprising at least one of the polysilazanes having the formula 1 and/or formula 2 where n is an integer and is dimensioned such that the perhydropolysilazane has a number-average molecular weight of 150 to 150 000 g/mol, a solvent and a catalyst and, if desired, one or more cobinders, for preventing scaling and corrosion on metal surfaces. The hardened coating has a thickness of 0.2-10 micrometers, preferably 0.3 to 5 micrometers. It is particularly useful as a protective coating for metals for preventing scaling and corrosion.
