Abstract

A high molecular weight poly(dipropylenecarbonate-co-disiloxane) was prepared through a simple acid-catalyzed hydrolysis and condensation polymerization reaction of bis(3-dimethylethoxysilylpropylene) carbonate. The polymer was thermally stable to 300 °C. Higher temperatures resulted in the complete degradation of the polymer to monomeric products including three different tetramethyldisiloxane products. The nature of degradation products were markedly dependent on the manner in which the polymer had been processed and were particularly sensitive to traces of acid.
