Abstract
PURPOSE: When the pyrolytic polycondensation reactions of an organosilicon compound is conducted by heating, a specific amount of hydrogen is added to the reaction system, thus forming an organosilicon polymer containing silicon and carbon atoms as the main chain components with narrow molecular weight distribution.
CONSTITUTION: An organosilicon compound, preferably a cyclic polysilane of formula I (R1, R2 are H, alkyl, aryl, silyl; n is 4 or more) or a chain polysilane of formula II (R3, R4 are H, alkyl, aryl, silyl, hydroxyl, alkoxy group; R5, R6 are H, alkyl, aryl, silyl; m is 2 or more), is heated to effect pyrolytic polycondensation to produce a polymer containing silicon and carbon atoms as the main chain components wherein hydrogen is added to the reaction system and the reaction is conducted under a hydrogen partial pressure of 20W100kg/cm2 at 25°C.
