Abstract
The present invention relates generally to a novel process for making a solid solventless MQ resin comprising the steps of (1)(A) feeding at least one MQ resin dispersed in a volatile solvent into an extrusion device, (2) removing the volatile solvent to form a solid solventless MQ resin; and (3) recovering the solid solventless MQ resin, provided steps (1) to (3) are completed without the addition of a linear silicone fluid.
