    Abstract: The present invention is related to the preparation and use of moderately cross-linked (chin-extended), reverse (or “inverted”) surfactants, wherein the reverse surfactants comprise a polyether backbone with oligomeric or polymeric silicon-containing substitutions along the backbone. The present invention further describes crosslinked versions of the inverted surfactants, reaction products of alkenyl (allyl, vinyl, methallyl) functional copolymers (polyethers), silicone hydrides and cross-linking agents, which may be optionally reacted with water to react the remaining alkoxy groups. The crosslinking agent contains either SiH or Si-alkoxy groups or both. The compounds of the present invention exhibit only moderate cross-linking in order to be soluble or dispersible in appropriate solvents.

    Abstract translation: 本发明涉及中等交联(下巴延伸),反向(或“倒”)表面活性剂的制备和使用,其中反向表面活性剂包含具有沿主链的低聚或聚合的含硅取代基的聚醚主链。 本发明进一步描述了反转表面活性剂的交联形式,烯基(烯丙基,乙烯基,甲代烯丙基)官能团共聚物(聚醚),硅氧烷氢化物和交联剂的反应产物,其可以任选地与水反应以反应剩余的烷氧基 。 交联剂含有SiH或Si-烷氧基或两者。 本发明的化合物仅显示适度的交联,以便在适当的溶剂中溶解或分散。
