Abstract
An improved process for the preparation of high viscosity (i.e., greater than 1 million mPa·s at 25° C.) silanol-terminated silicone polymers and copolymers, often referred to in the industry as silanol-terminated silicone polymer gums. The silanol-terminated silicone polymer gums are made by the ring-opening polymerisation of organocyclosiloxane oligomers (alternatively referred to as cyclic siloxane oligomers) using a conical screw dump extruder (). It also relates to silanol-terminated silicone polymer gums made by the process.
