摘要：
Acyclic diene metathesis (ADMET) polymerization of divinyltetramethyl-disiloxane in the presence of rhodium [RhCl(COD)](2) and ruthenium RuCl2(PPh3)(3) catalysts led predominantly to linear oligomers [M(n)=1815, M(w)/M(n) = 1.16] if the rhodium catalyst was used or to mixtures of dimeric and trimeric oligomers if the ruthenium complex was applied. The rhodium complex appeared to be the first effective catalyst for ADMET polymerization of divinyldisubstituted organosilicon compounds.
