Abstract
A chlorination reaction can be carried out at a relatively low temperature by heating a mixture of granular metallic silicon and metallic copper or a copper compound in an inert atmosphere even when the metallic silicon has a high purity and does not contain aluminum and titanium and that chloropolysilane of high purity can be obtained by further adding metallic silicon as needed after the chlorination reaction is started.
