Production of organopolysiloxane copolymers with a phenyl ether solvent |
摘要 |
An improved process is provided for the preparation of siloxane-oxyalkylene block copolymer surfactant compositions which utilize a hydrosilylation reaction with a phenyl ether as the reaction solvent and the use of a phenyl ether as a cold blend additive. Ethylene glycol phenyl ether is the preferred reaction solvent or cold blend additive.
