Abstract: The present technology provides compositions, methods, and processes to form polysiloxanes. In one aspect, the present technology provides a process for the ring opening polymerization of a cyclosiloxane comprising contacting a cyclosiloxane with a bicyclic guanidine compound. The guanidine-containing compounds useful in the ring opening reaction include a fused ring structure comprising a guanidine functional group as part of the fused ring.
