Abstract:
1. A polyether urethane containing composition comprising from 40 to 80 percent by weight based on polyether urethanes in the composition, of 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 and a maximum total degree of unsaturation of less than 0.04 milliequivalents/g (meq/g), wherein the reactive silane groups are incorporated by the reaction of an isocyanate group with a compound corresponding to the formula wherein X represents identical or different organic groups which are inert to isocyanate groups below 1000°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 and R
