Abstract
A both end hydro-terminated polysilane is of the formula: H[(R.sup.1 R.sup.2 Si).sub.n (R.sup.3 R.sup.4 Si).sub.m ].sub.k H wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently C.sub.1 -C.sub.12 alkyl groups or aryl groups and letters n, m and k are numbers in the range: 0.ltoreq.n.ltoreq.10, 0.ltoreq.m.ltoreq.10, n+m.gtoreq.10, and k.gtoreq.1. It is prepared by dissolving a corresponding chloro-terminated polysilane in a solvent and reducing with LiAlH.sub.4 in an inert gas atmosphere.
