    摘要: The invention provides a process for preparing emulsions of organopolysiloxanes (O), which includes polymerizing: (1) 100 parts by weight of hydroxyl-terminated organopolysiloxanes and (2) at least 0.01 part by weight of trialkylsilyl-terminated organopolysiloxanes having a viscosity of at least 55 mm2/s in the presence of (3) acidic catalyst and (4) emulsifier in an aqueous medium until the desired molecular size is reached.

    摘要: Aqueous silicone emulsions are prepared by emulsifying silicone, emulsifier, and water in a first high shear mixer, and introducing the viscous phase thereby obtained obtained, optionally with further components, into a second high shear mixture. A set point for temperature and pressure after each mixer is established, and the measured temperatures and pressures are used in a feedback loop to adjust process parameters such that the set points are maintained.
