Abstract
An organopolysiloxane compound containing per molecule at least one structural unit of the general formula O3-a/2RaSi—Y(SiRaO3-a/2)b (I) where R can be identical or different and denotes a monovalent SiC-bonded organic radical which has 1 to 30 C atoms and may contain one or more N and/or O atoms, Y is a divalent to dodecavalent organic radical which has 1 to 30 C atoms and may contain one or more O atoms, a is 0 or 1, and b is an integer from 1 to 11.
Claims15
A liquid organopolysiloxane compound having a viscosity of about 10 to about 10,000,000 mPa·s, and containing per molecule at least one structural unit of the formula
- O3-a/2RaSi—Y(SiRaO3-a/2)b (I)
- where
- R each are identical or different and are a monovalent SiC-bonded methyl, ethyl, phenyl, allyl, or vinyl radical which
- Y is a divalent to dodecavalent organic radical which has 1 to 30 C atoms and optionally contains one or more O atoms, wherein the ratio of C atoms in Y to the valence of Y is not more than 3
- a is 0 or 1, and
- b is an integer from 1 to 11,
- further comprising structural elements of the formula
- R1cSiO4-c/2 (II)
- where
- R1 each are identical or different and denote a monovalent SiC-bonded methyl, ethyl, phenyl, allyl, or vinyl radical, and
- c is 2 or 3.
