Patent ID: 8138277

Claim:
A method for preparing a composition, said composition comprising a reactive carrier material and a silane-modified urea derivative of formula (I) wherein X, in each instance independently, is NR 4 , S or O; R 1 is a linear or branched C 1 -C 12 -alkylene radical, a saturated or unsaturated C 6 -C 20 -cycloalkylene radical, a C 6 -C 20 -arylene radical which is unsubstituted or substituted with at least one C 1 -C 4 -alkyl substituent, or —C 6 H 4 —CH 2 —C 6 H 4 ; R 2 in each instance is independently is H or a C 1 -C 4 -alkyl radical; R 3 in each instance a C 1 -C 20 -alkyl or C 6 -C 20 -aryl radical; R 4 is H, C 1 -C 4 -alkyl or C 6 -C 20 -aryl radical; m is 1 or 3; n is from 0 to 10; and x is from 0 to 2, comprising reacting a diisocyanate of formula (II) OCN—R 1 —NCO (II) with a silane compound of formula (III) at a temperature of from 0 to 100° C., wherein X, R 1 , R 2 , R 3 , m, n and x are as defined above; wherein the reaction of the diisocyanate with the silane compound is carried out in the presence of the reactive carrier material; and wherein the reactive carrier material is a silylated polymer based on a polyether, a polyurethane, a polysulfide, a silicone, an acrylate, a methacrylate or a mixture thereof.
