Abstract
Disclosed is a process for the production of a polysilazane containing Si--N linkages in the main chain thereof. According to the present invention, the polysilazane is produced by reacting a polyaminosilane compound with a polyhydrogenated nitrogen-containing compound in the presence of a basic catalyst or by reacting a polyhydrogenated silicon compound with a polyhydrogenated nitrogen-containing compound in the presence of a basic solid oxide catalyst.
