    摘要: Silicone polyethers are prepared in a two stage process by reacting an unsaturated polyether with a first Si—H functional organopolysiloxane and then with a second organopolysiloxane, in which the weight ratio of silicon bonded hydrogen in the first and second organopolysiloxanes is at least 0.9. The reaction is more rapid than a single step process and produces a product with less unreacted Si—H content.
