| 摘要 |
The present invention relates to the organopolysiloxanes having the formula [R1Si(OSiR22X)2OSiR22O1/2]a[R3SiO1/2]b[R2SiO]c[RSiO3/2]d[SiO2]e(1), where R is optionally substituted C1- to C18-hydrocarbon radicals, R1 is an optionally substituted C6- to C15-hydrocarbon radical having at least one phenyl ring, R2 is a C1- to C3-hydrocarbon radical, X is a hydrogen atom or an organic or organosilicon functional group bonded via a divalent, optionally substituted C2- to C15-hydrocarbon radical, with one or more methylene units of the hydrocarbon radical being able to be replaced by oxygen atoms bonded on both sides to carbon atoms, a is an integer of at least 1 and b, c, d and e are each 0 or a positive integer, and the sum of a, b, c, d and e is at least 3, and the process for the preparation thereof.
