A method for the solvent-free, continuous production of organopolysiloxane/polyurea/polyurethane block copolymers involves reacting amino-functional siloxanes with polyisocyanates and organic polyhydroxy compounds. The organopolysiloxane/polyurea/polyurethane block copolymers produced by means of the inventive method are useful for numerous purposes, for example as elastomers, caulks, sealants, and films.
