Abstract
A method of producing an oligofuran moiety-containing polycarbosilane, the method including a polymerization step of reacting a dihydrosilyloligofuran compound with a diene compound and/or diyne compound in the presence of ahydrosilylation catalyst in which method the dihydrosilyloligofuran compound being a compound having a 2- to 256-mer of a furan ring and a hydrosilyl group at the α-position of each of both terminal furan rings of the 2- to 256-mer of the furan ring.
