Abstract
A polysilane having excellent functionalities (e.g., solubility in a solvent and reactivity) is obtained by introducing a structural unit of the following formula (1) to a polysilane through a reaction of a dihalosilane having a Si—H bond and adding a hydrosilylatable compound (e.g., a compound having a carbon-carbon unsaturated bond) to the Si—H bond, wherein R1 represents a hydrogen atom, an organic group, or a silyl group; and “n” denotes an integer of not less than 1.
Claims18
