Abstract:
1. A process for producing 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, where each MQ resin has the general formula (I) R (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 having a general formula (II): (R′ 3 SiO 1/2 ) x (R′ 2 SiO 2/2 ) y (R′SiO 3/2 ) z where x and y are positive numerical values and z is 0 or a positive numerical value with the provisos that x+y+z=1, y/(x+y+z)>0.8 and R′ is a functional or nonfunctional, substituted or unsubstituted organic radical, and the DP is greater than 10.
