Abstract
The invention relates to a silane of the formula (1), Si(R1)m(R2)n(R3)4-(m+n) (1) as defined herein, where the silane has at least one group of the general formula (3): as defined herein, to a method for preparing the silane, and to curable compositions, containing the silane and at least one polyorganosiloxane.
Claims15
A silane of the formula (1),
- Si(R1)m(R2)n(R3)4-(m+n) (1)
- where
- each m is independently 0 or 1, each n is independently 0, 1, 2, or 3, and the sum n+m is a maximum of 3;
- each R1 independently stands for:
- a substituted or unsubstituted alkyl, alkenyl or alkynyl group,
- a substituted or unsubstituted cycloaliphatic group or aryl group, or
- a substituted or unsubstituted heteroalicyclic group or heteroaryl group;
- each R2 independently stands for a group of the general formula (2):
- where
- each R4 independently stands for:
- hydrogen, or
- a substituted or unsubstituted alkyl, alkenyl, or alkynyl group;
- R5 stands for:
- a substituted or unsubstituted alkyl, alkenyl, or alkynyl group, or
- a group of the general formula (2-2):
- —OR5-2 (2-2)
- where
- R5-2 stands for:
- a substituted or unsubstituted alkyl, alkenyl, or alkynyl group;
- or
- a group of the general formula (2-3):
- where
- R5-3 stands for:
- a substituted or unsubstituted alkyl, alkenyl, or alkynyl group;
- each R3 independently stands for a group of the general formula (3):
- where
- each R6 independently stands for:
- hydrogen or a substituted or unsubstituted alkyl, alkenyl, or alkynyl group;
- R7 stands for:
- hydrogen,
- a substituted or unsubstituted alkyl, alkenyl, or alkynyl group,
- a substituted or unsubstituted cycloaliphatic group or aryl group,
- R8, or
- a group —(CH2)q—COOR9, where p is an integer from 2 to 10, and R9 stands for a substituted or unsubstituted alkyl, alkenyl, or alkynyl group, or a substituted or unsubstituted cycloaliphatic group or aryl group;
- R8 stands for a group of the general formula (4):
- —R10—SiR11o(OR12)3-o (4)
- where
- o independently stands for 0, 1, or 2,
- R10 stands for an alkylene group, optionally interrupted by a heteroatom,
- each R11 independently stands for a substituted or unsubstituted alkyl, alkenyl, or alkynyl group,
- each R12 independently stands for:
- a substituted or unsubstituted alkyl, alkenyl, or alkynyl group,
- an acyl group;
- or a group of the formula (5):
- where
- each R13 independently stands for:
- hydrogen;
- or
- a substituted or unsubstituted alkyl, alkenyl, or alkynyl group;
- R14 stands for:
- a substituted or unsubstituted alkyl, alkenyl, or alkynyl group.
