Abstract
A method for producing polysilanes comprising subjecting a dihalosilane of the general formula ##STR1## (wherein m is 1 to 3; R represents hydrogen atom, alkyl group, aryl group, alkoxy group, amino group or silyl group and two Rs are the same or different in case of m=1, four Rs are the same or at least two of them are different in case of m=2 and six Rs are the same or at least two of them are different in case of m=3; X represents halogen atom) to the action of Mg or Mg alloy in an aprotic solvent in the presence of Li salt and metal halide, thereby producing polysilane represented by the general formula ##STR2## (wherein R is as defined above corresponding to the starting material; n is 2 to 1000).
