An organopentasiloxane having the formula
A-R¹-SiMe₂(OSiMe₂)₃OSiR²(3-n)(OR²)n
wherein Me denotes a methyl radical; A is a group selected from the group consisting of methacryloxy, glycidoxy and amino; R¹ is a divalent organic group selected from the group consisting of an alkylene group having at least 2 carbon atoms and an alkyleneoxyalkylene group; R² is independently selected from monovalent hydrocarbon groups free of aliphatically unsaturated bonds; and n is an integer having a value of 1 to 3, and methods for the preparation thereof, are disclosed.
一种有机五硅氧烷,其式为
A-R¹-SiMe₂(OSiMe₂)₃OSiR²(3-n)(OR²)n
其中,Me 表示甲基;A 是选自甲基丙烯酰氧基、缩水甘油氧基和氨基的基团;R¹ 是选自至少具有 2 个碳原子的亚烷基和亚烷氧基烷基的二价有机基团;R² 是独立选自不含脂肪不饱和键的单价烃基;n 是数值为 1 至 3 的整数,本发明公开了这些基团及其制备方法。
