Abstract
The present invention provides polishes for surfaces, comprising aminoorganopolysiloxanes (A) which are solid at room temperature, contain fluoro groups and are able to change their aggregate state reversibly as a result of changes in temperature.
Claims19
A polish for surfaces, comprising at least one aminoorganopolysiloxane (A) which is solid at room temperature, contains fluoro groups, is able to change its aggregate state reversibly as a result of changes in temperature, contains at least one aminoorgano group per molecule, and has a liquidity point or melting point between 20° C. and 60° C.
A polish for surfaces, comprising at least one aminoorganopolysiloxane (A) which is solid at room temperature, contains fluoro groups is able to change its aggregate state reversibly as a result of changes in temperature wherein said aminoorganopolysiloxane (A) comprises units of the general formula I
- AaRbSiXcO(4-a-b-c)/2 (I),
- where
- R are independently monovalent, optionally substituted hydrocarbon radicals having 1 to 40 carbon atoms,
- X are independently chlorine or a radical of the formula —OR1 where R1 is hydrogen or an alkyl radical having 1 to 8 carbon atoms, optionally substituted by ether oxygen atoms, or X is a radical of the general formula II
- —R2{[CH(CH3)CH2O]e[CH2CH2O]f[(CH2)4O]gR3}y−1 (II),
- where
- R2 is a divalent, trivalent or tetravalent hydrocarbon radical having 2 to 30 carbon atoms optionally interrupted by oxygen atoms and substituted by one or more groups of the formulae
- —C(O)—O—, —C(O)—NR3—, —SO2—NR3—, —NR3—, —N═ and —S—
- y in accordance with the valence of radical R2 is 2, 3 or 4,
- R3 is hydrogen or a hydrocarbon radical which has 1 to 40 carbon atoms and is optionally substituted by a group —C(O), and
- e, f and g independently of one another, are 0 or an integer from 1 to 200, with the proviso that the sum e+f+g is ≧1,
- A is a radical of the general formula III
- —R4{—CnF2n+1}y−1 (III),
- where
- R4 has the same definition as R2,
- y in accordance with the valency of radical R4 is 2, 3 or 4 and n is a number from 1 to 40,
- a is 0, 1 or 2,
- b is 0, 1, 2 or 3, and
- c is 0, 1, 2 or 3,
- with the proviso that the sum a+b+c is ≦4,
- aminoorganopolysiloxane (A) has at least one radical A per molecule, contains at least one aminoorgano group per molecule, and has a liquidity point or melting point between 20° C. and 60° C.
A polish comprising at least one aminoorganopolysiloxane which is solid at room temperature, contains fluoro groups, and is able to change its aggregate state reversibly as a result of changes in temperature, said at least one aminoorganopolysiloxane having the formula
- EhR3-hSiO(SiR2O)o(SiREO)mSiR3-hEh (IX),
- where
- h is 0, 1, or 2
- m and o independently are 0 or an integer from 1 to 1000,
- R is a monovalent, optionally substituted C1-40 hydrocarbon radical,
- E is a radical of the formula
- —R5—(NR6—CH2—CH2)d—NR62
- wherein
- R5 is a divalent, optionally substituted C1-12 hydrocarbon radical,
- R6 is hydrogen, methyl, ethyl, propyl, or butyl
- d is 0 or an integer from 1-8, wherein at least one R6 is H,
- and wherein said at least one aminoorganopolysiloxane contains at least one group E, and has a liquidity point or melting point between 20° C. and 60° C.
