ABSTRACT:
The present invention relates to a polyether urethane containing one reactive silane group and one or more polyether segments having a number average molecular weight of 1000 to 15,000, wherein the reactive silane groups are incorporated by the reaction of an isocyanate group with a compound corresponding to the formulawhereinX represents identical or different organic groups which are inert to isocyanate groups below 100° C., provided that at least two of these groups are alkoxy or acyloxy groups,Y represents a linear or branched alkylene group containing 1 to 8 carbon atoms andR1represents an organic group which is inert to isocyanate groups at a temperature of 100° C. or less.
