PURPOSE:To obtain a high polymer substance capable of being converted into an inorganic compound having a TiC crystalline structure consisting of Ti, C and O by calcination, by reacting a specific polysilane with a titanium alkoxide under heating. CONSTITUTION:(A) A polysilane having 100-600 molecular weight and a structural unit shown by the formula (R is H, lower alkyl, phenyl, hydroxyl group, or halogen) or a polysilane having this structural unit linked by a carbosilane bond or siloxane bond is reacted with (B) a titanium alkoxide shown by the formula Ti(OR') (R' is alkyl) in a ratio of number of atoms of Ti in the component B to number of atoms of Si in the component A of (5:1)-(1:1) in an inert atmosphere optionally in the presence of a small amount of water under heating, to give the desired high polymer substance having 2X10<2>-10<7> molecular weight and absorption of visible spectrum at 370-1,200nm. |
