Abstract
Hydrosilylation of allyl carbamates by poly (methylhydrosiloxane) (PMH S) catalyzed by platinum- or rhodium-based complexes was investigated. About 10% of the carbamate molecules decompose during the hydrosilyla tion reaction through the cleavage of the carbamate bond. A redistribu tion process also takes place among the polysiloxane chains resulting in the formation of branched polymers but no crosslinking occurs. A me chanism for this side-reaction is proposed.
