Abstract
The present invention relates to a method for producing an organooxysilyl-crosslinked polymer by reacting a polyether carbonate polyol which contains carbon-carbon double bonds with a polysiloxane compound in the presence of a suitable catalyst. Suitable polysiloxane compounds have at least two Si—H bonds. This invention also relates to organooxysilyl-crosslinked polymers which are formed by this process.
Claims14
A process for preparing an organooxysilyl-crosslinked polymer, comprising reacting a polyethercarbonate polyol containing carbon-carbon double bonds with a polysiloxane compound in the presence of a catalyst (A), wherein the polysiloxane compound has at least two Si—H bonds.
