MANUFACTURE OF ORGANOPOLYSILOXANE SURFACTANT |
摘要 |
An improved process is provided for the preparation of siloxane-oxyalkylene block copolymer surfactant compositions which utilized a hydrosilation reaction with high boiling point polar polyols 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. Dipropylene glycol is the preferred polar solvent and when used in the preparation of the surfactants need not be removed when the surfactants are employed in the preparation of urethane foams. |
