Abstract

In a first stage, the aminolysis of a dichlorosilane and/or of a dichlorodisilane is carried out and the amine chloride formed is removed and, in a second stage, the aminolysate obtained during the first stage is reacted with at least one organosilicon compound chosen from an organochlorosilane, an organochlorodisilane, an organochloropolysilazane and an organochloropolydisilylsilazane containing at least three chlorine atoms per molecule, in the presence of a tertiary amine. A cationic polymerisation may be advantageously optionally carried out on the aminolysate obtained in the first stage. The polysilazanes thus treated exhibit a high heat resistance and can be employed especially as precursors of ceramic products, with a high yield of mineral product.
