FUNCTIONALIZED HYDROXYSILANES, SILYLATED POLYURETHANES, AND COMPOSITIONS COMPRISING SAME

The present invention relates to a compound of formula (I): and also to the process for preparing same, and to the uses thereof. The present invention also relates to the polyurethanes obtained from the compounds of formula (I), and also to the uses of said polyurethanes.

Organosilane esters having glycol ether moieties

The present invention relates to new organosilane esters which can be characterized by the formula Y-(CH2)n Si(CH3)p -Xm Z3-(m+p). In this formula, Y represents either a substituted or unsubstituted amino group, or it represents the mercapto moiety or the moiety STR1 X represents an alkoxy group with 1 to 4 carbon atoms and Z a glycol ether moiety. The index n can assume the numerical values from 1 to 3, m can be 0 or 1 and p can be 0 or 1 or 2, on the condition that m+p is equal to or less than 2. The new silanes yield very stable hydrolyzates and have good adhesion-improving properties. They are therefore particularly well suited for use in sealing compositions.
