Preparation and Properties of eta 6-Tricarbonylchromium - Complexed Arylenesiloxane Polymers.
Abstract
Poly(tetramethyl-p-silphenylenesiloxane), 1, and poly(methylphenylsiloxane), 2, were prepared and subsequently reacted with hexacarbonylchromium to generate their eta 6-Cr(CO)3 complexed analogs 3 and 4 respectively. During the complexation reaction, competing decomposition to chromium salts took place. Furthermore a competing chain scission reaction took place resulting in lower molecular weights for the complexed polymers. Heating 3 and 4 resulted in carbon monoxide evolution and the presence of eta 6-Cr(CO)3 moieties lowered the thermal stability of the polymers.
