具体的氨基烷基官能的烷氧基硅氧烷-低聚物混合物，其制备方法及其用途
摘要：
本发明涉及具体的混合物，其包含通式I的链状的氨基丙基官能的烷氧基硅氧烷和/或通式II的环状的氨基丙基官能的烷氧基硅氧烷：其中基团R彼此独立地由下述基团构成：(i)下式的氨基丙基官能团：-(CH2)3-NH2、-(CH2)3-NH(CH2)2-NH2和/或-(CH2)3-NH(CH2)2-NH(CH2)2-NH2，(ii)甲氧基和/或乙氧基，和(iii)任选的丁基或者辛基，m是整数2-30，和n是整数3-30，其中在式I以及 II的化合物的任一硅原子上键合有最多一个氨基烷基官能团，和其中Si与烷氧基的摩尔比的商至少是0.3，涉及其制备方法。它们出色地适合用于粘合-和密封剂中，并且在此的特点是改进的粘附性，特别是在难以彼此粘合的基底上的粘附性。
摘要（英）：

The present invention relates to specific mixtures containing straight-chain aminopropyl-functional alkoxysiloxanes of the general formula I and/or cyclic aminopropyl-functional alkoxysiloxanes of the general formula II (R)3Si-O-[Si(R)2-O]m-Si(R)3 (I), (II), in which the groups R are composed mutually independently of (i) aminopropyl-functional groups of the formula -(CH2)3-NH2, -(CH2)3-NH(CH2)2-NH2 and/or -(CH2)3-NH(CH2)2-NH(CH2)2-NH2, (ii) methoxy and/or ethoxy groups and (iii) optionally butyl or octyl groups, m is an integer from 2 to 30 and n is an integer from 3 to 30, where there is at most one aminoalkyl-functional group bonded to a silicon atom of a compound of the formula I and/or II, and where the quotient calculated from the molar ratio of Si to alkoxy groups is at least 0.3, and a process for producing same. These have excellent suitability for application as adhesives and sealants, while featuring improved adhesion more particularly on substrates that are not easily bonded to one another.
