Page/Page column 11, (2008/06/13)
Organoalkoxysilane compound (I), is new. Organoalkoxysilane compound (I) of formula (R 1>-NH-C(=X)-Y 1>-R 2>-Si(R 3>) a-(OR 4>) 3-a), is new. R 1>optionally substituted alkyl-, cycloalkyl-, aryl- or arylalkyl, optionally containing heteroatoms, and contains polymerizable double bonds neither with water nor with silane reactive groups yet amino groups; R 2>optionally cyclic, 1-20C alkyl optionally with aromatic portions and with heteroatoms; R 3>1-8C alkyl; R 4>1-5C alkyl; a : 0-2, preferably 0 or 1; X : O or S; Y 1>O, S or N-R 5>; and R 5>1-20C hydrocarbon, which exhibits cyclic portions and optionally exhibits at least one functional group such as alkoxysilyl, ether, sulfone, nitrile, nitro, carboxylic acid ester, sulfonic acid ester or phosphonic acid ester. Independent claims are included for: (1) the preparation of (I); (2) a composition comprising (I); (3) humidity-hardening composition comprising (I) and at least one silane and or isocyanate-functional polymer; (4) adhered article, which is obtained by adhesing a first substrate and a second substrate together with a composition, where both the substrates consists of different or same materials; and (5) sealed article, which was sealed by the application of a composition between the surfaces of a first substrate and a second substrate, where the substrates consist of different or same materials.
Compounds containing alkoxysilane and amino groups

N-alkoxysilylalkyl-aspartic acid esters are prepared by the reaction of equimolar quantities of amino-alkyl alkoxysilanes with maleic or fumaric acid esters. These N-alkoxysilylalkyl-aspartic acid esters are particularly useful as reactants in the preparation of prepolymers containing alkoxysilane and urea groups.
