Abstract:
1. A process for producing silicone copolymers, comprising the steps of: (a) providing at least one multi-stage blade-mixed plug flow reactor having an entry and an exit; (b) continuously feeding (i) hydrogen siloxane, (ii) olefinically substituted polyether or olefin capable of reacting with said hydrogen siloxane, and (iii) catalyst for the reaction to the entry of the multi-stage blade-mixed plug flow reactor; and (c) continuously withdrawing from the exit of the multi-stage blade-mixed plug flow reactor a stream that comprises silicone copolymer and is substantially free of unreacted hydrogen sioxane, provided that said hydrogen sioxane and said polyether or olefin have a residence time at reaction temperature in the multi-stage blade-mixed plug flow reactor sufficient to effect substantially complete hydrosilation.
