The invention relates to new alkoxyamines suitable for hydrosilylation reactions, to siloxane modified alkoxamines and to siloxane modified polymers and to their use as slip and leveling agent or as dispersant. The alkoxamines are compounds of formula (I) or (II) wherein A is a group capable of forming a stable free nitroxyl radical A. which is bound via its oxygen atom to the carbon atom; R1 and R2 independently of one another are hydrogen, C1-C18-alkyl, C3-C8cycloalkyl or phenyl which are unsubstituted or substituted by NO2, halogen, amino, hydroxy, cyano, carboxy, C1-C4alkoxy, C1-C4alkylthio, C1-C4alkylamino or di(C1-C4alkyl)amino; R3, R4 and R5 independently of one another are hydrogen or C1-C18alkyl or phenyl; or R3 and R5 together with the linking group C=C form a 5 to 12 membered ring; R6 is hydrogen or C1-C18alkyl or phenyl; X is O, NH or NR7, wherein R7 is C1-C18alkyl, C3-C8cycloalkyl or phenyl; Y is a direct bond, C1-C30alkylene or C6-C12arylene, with the proviso that the compound of formula (I) is not (1) or (2). |
