Abstract
The invention is directed to a polysilane represented by the formula (1) ##STR1## PA1 wherein R is hydrogen atom, alkyl group, aryl group, alkoxy group, amino group or silyl group, R's may be the same or at least two of them may be different from each other; each hydroxyl group is in the p-position or m-position; and n is 2 to 10,000, preferably 13 to 8,500. The polysilane of the invention is important as materials for modified polycarbonates or like engineering plastics, resists or electrophotographic photoreceptors.
