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. The reaction solvent need not be removed from the block copolymer, particularly when the block copolymer is used as a surfactant for polyurethane foam formulations. Ethylene glycol phenyl ether is the preferred reaction solvent.
