Abstract
The invention relates to organosilicon compounds with at least three silicon atoms, consisting of units of the formula (I) R,Si(NR,C═ONR,),(NR,C═ONR,),Y,O,[(CR,),],, where Y represents units of the formula (II) —SiR,(NR,C═ONR,),(NR,C═ONR,),, where R, R,, R,, R,, R,, R,and R,independently of each other can be either identical or different and represent a hydrogen atom or possibly substituted monovalent hydrocarbon radicals with between 1 and 20 carbon atoms; and where a, k, t, n, m, r, s, p and q have the meaning assigned to them in claim,, under the provision that the sum of p+q is ≦3, the sum of a+k+l+m+n+r equals 4, the sum of m+r equals 0 or 1, and the organosilicon compound of the invention contains at least one unit of formula (I) where t is not equal to 0.
