ABSTRACT:
The present invention relates to 1-alkoxy-polyalkyl-piperidine derivatives containing a structural element of formula (I)G1, G2, G3, G4are independently C1-C6alkyl with the proviso that at least one is not methyl or G1and G2or G3and G4, or G1and G2and G3and G4together form a C5-C12cycloalkyl group; G5, G6independently are H, C1-C18alkyl, phenyl, naphthyl or a group COOC1-C18alkyl and X represents a group such that the free radical X● derived from X is capable of initiating polymerization of ethylenically unsaturated monomers, with the proviso that compounds A1 and A2 are excludedFurther subjects of the invention are a polymerizable composition comprising a) at least one ethylenically unsaturated monomer and b) a 1-alkoxy-polyalkyl-piperidine derivative, a process for polymerizing ethylenically unsaturated monomers, and the use of 1-alkoxy-polyalkyl-piperidine derivatives for controlled polymerization. The intermediate N-oxyl derivatives, a composition of the N-oxyl derivatives with ethylenically unsaturated monomers and a free radical initiator X●, as well as a process for polymerization are also subjects of the present invention.
