Abstract
Organosilicon high molecular weight compounds having silicon and carbon as the main skeleton components and consisting of a mixture of linear polycarbosilanes having silicon and carbon as the main skeleton components, cyclic polycarbosilanes having silicon and carbon as the main skeleton components and polycarbosilanes in which linear carbosilane and cyclic carbosilane are chemically bonded are produced by thermally decomposing and polycondensing at least one of organosilicon compound having polysilane skeleton selected from the group consisting of cyclic polysilanes shown by the following formula (R.sub.1.R.sub.2.Si)n, n.gtoreq.4 wherein R.sub.1 and R.sub.2 are hydrogen, alkyl group, aryl group, silyl group, or a halogen and linear polysilane shown by the following formula ##STR1## WHEREIN R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are hydrogen, alkyl group, aryl group, silyl group or a hologen, by heating at a temperature of 300.degree.-2,000.degree. C under at least one atmosphere of an inert gas and hydrogen gas or under a vacuum.
