    摘要: Novel silicone polyether copolymers of inverse structure of the formula 1, characterized in that no unsaturated functional groups caused by side reactions or conversion products thereof are present in the copolymer, and a process for preparation thereof, in which a polyether modified terminally and/or laterally with alkoxysilyl groups is reacted with silanes and/or siloxanes which bear one or more hydrolysis-labile groups, in a hydrolysis and condensation reaction.
