Acyclic diene polymerization (ADP) of divinyldimethylsilane in the presence of ruthenium RuCl2(PPh(3))(3) and rhodium [RhCl(cod)](2) catalysts led predominantly to linear silylene vinylene oligomers (M(n) = 1510 and M(w)/M(n) = 1.19) if the ruthenium catalyst was used or to mixture of cyclic and linear oligomers if rhodium complex was catalyst.
