    • The invention provides organopolysiloxanes obtained by A) addition reaction of organopolysiloxanes containing SiH groups with vinylsiloxanes in the presence of platinum catalysts or rhodium catalysts, with the proviso that the organopolysiloxanes are present in a molar excess of at least 6 times, relative to the vinylsiloxane, and further reaction of the reaction product in at least one of the following stages: B) transition metal-catalyzed partial or complete addition reaction of the SiH groups with alkenyl and/or alkynyl compounds, C) with the use of a catalyst, partial or complete reaction of the RSiH groups, remaining after above reaction(s), with at least one alcohol from the group of linear or branched, saturated, mono- or polyunsaturated, aromatic, aliphatic-aromatic, optionally halogen atom-containing monoalcohols, polyether monoalcohols, polyester monoalcohols, and amino alcohols.
    • 本发明提供了通过以下步骤获得的有机聚硅氧烷:A)在铂催化剂或铑催化剂存在下,含有SiH基的有机聚硅氧烷与乙烯基硅氧烷的加成反应,条件是相对于乙烯基硅氧烷,有机聚硅氧烷的摩尔过量至少为6倍, 以及反应产物在至少一个以下阶段中的进一步反应:B)SiH基团与烯基和/或炔基化合物的过渡金属催化的部分或完全加成反应,C)使用催化剂,部分或 与上述反应后残留的RSiH基团与来自直链或支链,饱和,单或多不饱和,芳族,脂族 - 芳族,任选含卤素的一元醇,聚醚一元醇的至少一种醇完全反应 ,聚酯一元醇和氨基醇。
