    Abstract: The invention relates to a method for producing granules from thermoplastic siloxane polymers, especially organopolysiloxane/polyurea/polyurethane block copolymers, by (d) transporting the thermoplastic siloxane polymer, especially organopolysiloxane/polyurea/polyurethane block copolymer, to which optionally additional additives were admixed, from the reactor to a cooling medium having a temperature ranging from -20 °C to 60 °C and (e) directly granulating and pelletizing the polymer in the cooling medium, at the same time or immediately after the polymer enters or has entered the cooling medium.
