Abstract

A co-grafted polymer comprising units of organopolysiloxanes with OH functional groups, polyesters and vinyl monomers, polymeric units of the vinyl monomers being linked to the organopolysiloxane and polyester units, is produced by polymerizing a suitable monomer dispersion. The product is suited for replacing all or some of the organopolysiloxane component in room temperature curable compositions containing organopolysiloxanes, silane cross-linking agents and a curing catalyst.
