摘要

Alkoxysilyl group containing polyether alcohol compounds (VIII), are new, provided that (VIII) excludes e.g. methoxy silane compound (IXa)-(IXd). Alkoxysilyl group containing polyether alcohol compounds of formula (VIII), are new, provided that (VIII) excludes methoxy silane compound of formula (OH-((C 3H 6)O) n-CH 2-CH(OH)-CH 2-O-(CH 2) 3-Si(OCH 3) 3) (IXa), (Si(OCH 3) 3-(CH 2) 3-O-CH 2-CH(OH)-CH 2-O-((C 3H 6)-O) n-CH 2-CH(OH)-CH 2-O(CH 2) 3-Si(OCH 3) 3) (IXb), (OH-(CH 2-CH 2-O) n-CH 2-CH(OH)-CH 2-O-(CH 2) 3-Si(OCH 3) 3) (IXc), or (CH 3-(CH 2) 1 1-O-(CH 2-CH 2-O) n-CH 2-CH(OH)-CH 2-O-(CH 2) 3-Si(OC 2H 5) 3) (IXd). R 1optionally saturated, optionally branched residue, a polyether residue of an alkoxy-, arylalkoxy- or alkylarylalkoxy group, with which the carbon chain can be interrupted by O, polyetheralkoxy residue, or one or several times annealated phenol group, preferably a polyether fragment, in which at least a fragment is inserted under the ring opening of (I)-(VI) into the obtained modified polymer chain, provided that the fragment obtained from the ring opening of (I), is not terminal; d : 1-1000, preferably greater than 4; e-g : 0-10000, preferably greater than 0; h-j : 0-500, provided that the fragments with the indices d-j are free of permutation, preferably greater than 0; R : saturated, one or more times unsaturated 1-20C-alkyl or 1-20C-haloalkyl; either a : 1-3; and b : 0-2; or a+b : 3; c : 0-24; p : a whole number, which is the difference of 4-a-b; R 2, R 3H, or saturated or optionally one or more times unsaturated, further substituted, optionally mono- or poly- valent 1-20C-hydrocarbon; R 5, R 6H, saturated or optionally one or more times unsaturated, further substituted, optionally mono- or poly- valent hydrocarbon, or cycloaliphatic hydrocarbon, which is optionally bridged over the fragment Y 1; Y 1CH 3bridge with 1 or 2 CH 3units; R 4a glycidyloxypropyl group, which is bonded over an ether- or ester function at linear or branched bounded 1-24C-alkyl or an aromatic or cycloaliphatic residue; n : 2-8; R 7, R 8H, alkyl-, alkoxy-, aryl- or aralkyl group; R 9-R 1 2H, alkyl-, alkenyl-, alkoxy-, aryl or aralkyl- group, where the cycloaliphatic or aromatic alkyl or alkenyl residue is bridged over Z fragment; and Z : divalent alkylene or alkenylene residue. An independent claim is included for the preparation of (VIII). [Image].
