✦ Synopsis
Acyclic diene polymerization (ADP) of divinyldimethylsilane in the presence of ruthenium RuCl,(PPh,), and rhodium [RhCl(cod)I2 catalysts led predominantly to linear silylenevinylene oligomers ( M , = 1510 and M J M , = 1.19) if the ruthenium catalyst was used or to mixture of cyclic and linear oligomers if rhodium complex was catalyst. 0
