A polysilane of Formula [I] or [II]: ##STR1## (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, R.sup.12, R.sup.13 and R.sup.14 denote independently hydrogen, alkyl, aryl, alkenyl, alkynyl, silyl, and amino groups. R.sup.1 and R.sup.2, R.sup.3 and R.sup.4, R.sup.5 and R.sup.6, R.sup.7 and R.sup.8, R.sup.13 and R.sup.14, R.sup.10 and R.sup.11 can form a ring with the silicon bonded to each group. m is 0 or 1. n is an integer.); and a method for synthesizing the polysilane of Formula [I] or [II] in which a small-ring polysilane is reacted (in a solvent) with an organolithium reagent, and then treated with silanes possessing a leaving group. The resulting polysilanes have a homogeneous molecular weight distribution and are useful as a functional polymer for nonlinear optical materials and electroconductive polymers.
