Abstract

The present invention provides specific alkoxylation products, a process for preparing them, compositions which comprise these alkoxylation products, and the use thereof.

First claim

1 . An alkoxylation product having intrinsically reduced viscosity, the alkoxylation product comprising the formula (I)
M i D j T k Q l UR u AP v   formula (I),
where the fragments M, D, T and Q are linked not to one another but instead with one another via the groups UR and/or AP, and the groups UR and AP are linked not to one another but instead with one another, correspondingly, via the fragments M, D, T or Q, i=0 to 16, j=0 to 10, k=0 to 6, l=0 to 4, u=0 to 17, v=0 to 6, with the proviso that i+j+k+l>=1, M independently at each occurrence is an oxygen-radical-carrying hydrocarbon radical having a minimum numerical molar mass of 88 g/mol, which may optionally be interrupted by heteroatoms,
or is a radical of the formula (Ia) or of the formula (Ib) or of the formula (Ic) with

where
a=0 to 1000,
b=1 to 1000,
c=0 to 1000,
d=0 to 1000,
w=an integer from 0 to 1000,
x=0 to 1000,
y=an integer from 0 to 500,
e=1 to 10,
f=0 to 2,
g=1 to 3,
with the proviso that g+f=3 and g is at least 1,
h=0 to 10
and with the proviso that the various monomer units of the fragments with the indices a, b, c, d, w, x and y may be constructed blockwise among one another or else are subject to a statistical distribution and, moreover, are freely permutable among one another, it being disallowed for each of the groups with the indices w and y to follow itself or the other respective group,

R 12 =independently at each occurrence a saturated or unsaturated, aliphatic or aromatic hydrocarbon radical having 2 to 30 C atoms, whose chain may be interrupted by oxygen and may further carry functional groups such as, for example, carboxyl groups or hydroxyl groups, it being possible for the carboxyl groups to be esterified optionally with alcohols, preferably with methanol, ethanol, propanol, butanol or hexanol, and for the hydroxyl groups to be esterified optionally with acids, preferably with acetic acid, neodecanoic acid or butyric acid, and/or an alkaryl group having 7 to 30, with the proviso that there must be at least one branched structural element present,
R 13 , R 14 =independently at each occurrence hydrogen and/or an organic radical, preferably alkyl, alkenyl, alkylidene, alkoxy, aryl and/or aralkyl groups, or optionally R 13 and/or R 14 may also be absent, and, if R 13 and R 14 are absent, there is a C═C double bond instead of the radicals R 13 and R 14 ;

if the bridging fragment Z is absent, then

R 15 , R 16 =independently at each occurrence hydrogen and/or an organic radical, preferably alkyl, alkenyl, alkylidene, alkoxy, aryl and/or aralkyl groups, and, if one of the radicals R 13 or R 14 is absent, the respective germinal radical (i.e. R 15 if R 13 is absent, and R 16 if R 14 is absent) is an alkylidene radical,
