POLYORGANOSILOXANE COMPOSITIONS WITH METAL BASED N-HETEROCYCLIC CARBENE CONDENSATION REACTION CATALYSTS AND METHODS FOR THE PREPARATION THEREOF

摘要

A complex prepared by combining a metal compound and an N-heterocyclic carbene has catalytic activity for condensation reaction of polyorganosiloxane compositions. The composition includes the complex, a silanol functional compound having an average per molecule of one or more silicon bonded hydroxy moieties.
