Abstract:
1. Cyclodextrinyl-containing organosilicon compounds comprising units of the formula where A each is the same or different and is a radical of the formula where CD is a mono- or multivalent, derivatized or underivatized cyclodextrin residue, and R R each is the same or different and is a substituted or unsubstituted hydrocarbyl radical optionally interrupted by oxygen atoms, sulfur atoms and/or nitrogen atoms, X each is the same or different and is a radical of the formula —OR a is 0, 1 or 2, b is 0, 1, 2 or 3, c is 0, 1, 2 or 3, and d is 0, 1, 2 or 3, with the provisos that: the sum a+b+c+d is≦3; and the organosilicon compound has at least one A radical per molecule; in not more than 90% of units of the formula (I), is the sum of a+b+c+d equal to 0;
