    Abstract: A product obtainable by transferring groups of formula (G-I) being present in a block oligomer having a polydispersity {overscore (M)}w/{overscore (M)}n of 1 to 1.7 and corresponding to formula (I) to groups of formula (Gu-II), wherein R1 is a hydrocarbyl radical or —O—R1 is oxyl; said transfer is carried out by reaction of the block oligomer with a hydroperoxide in a hydrocarbon solvent in the presence of a peroxide decomposing catalyst; n is a number from 2 to 14; R2 is for example C2-C12alkylene; A is for example —N(R4)(R5); R4 and R5 are for example C1-C18alkyl; R is preferably a group of formula (G-I) and B and B* have one of the meanings given for A; with the proviso that in the individual recurrent units of formula (I), each of the radicals B, R and R2 has the same or a different meaning. The products are useful as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials, in particular synthetic polymers.
