One subject of the present invention is a polymerizable composition, comprising A polymerizable composition, comprising a) at least one ethylenically unsaturated monomer or oligomer, and b) a compound of formula (Ia) or (Ib) Image R1, R2, R3 and R4 independently of each other are C1-C18alkyl, C3-C18alkenyl, C3-C18alkinyl, C1-C18alkyl, C3-C18alkenyl, C3-C18alkinyl which are substituted by OH, halogen or a group -O-C(O)-R5, C2-C18alkyl which is interrupted by at least one O atom and/or NR5 group, C3-C12cycloalkyl or C6-C10aryl or R1 and R2 and/or R3 and R4 together with the linking carbon atom form a C3-C12cycloalkyl radical; with the proviso that if Q in formula (Ia) is a direct bond, -CH2- or CO, at least one of R1, R2, R3 or R4 is different from methyl; R5, R6 and R7 independently are hydrogen, C1-C18alkyl or C6-C10aryl; X represents a group having at least one carbon atom and is such that the free radical X~ derived from X is capable of initiating polymerization of ethylenically unsaturated monomers; Z, is O or NR8; R8 is hydrogen, OH, C1-C18alkyl, C3-C18alkenyl, C3-C18alkinyl, C1-C18alkyl, C3- C18alkenyl, C3-C18alkinyl which are substituted by one or more OH, halogen or a group -O- C(O)-R5, C2-C18alkyl which is interrupted by at least one O atom and/or NR5 group, C3- C12cycloalkyl or C6-C10aryl, C7-C9phenylalkyl, C5-C10heteroaryl, -C(O)-C1-C18alkyl, -O-C1- C18alkyl or -COOC1- -COOC1-C18alkyl; Q is a direct bond or a divalent radical CR9R10, CR9R10-CR11R12, CR9R10CR11R12CR13R14, C(O) or CR9R10C(O), wherein R9, R10, R11, R12, R13 and R14 are independently hydrogen, phenyl or C1-C18alkyl; with the proviso that the compounds (A) and (B) are excluded Image Further aspects of the invention are a process for polymerizing ethylenically unsaturated monomers, and the use of heterocyclic alkoxyamine compounds for controlled polymerization. The intermediate N-oxyl derivatives, a composition of the N- oxyl derivatives with ethylenically unsaturated monomers and a free radical initiator, as well as a process for polymerization are also subjects of the present invention. Still further subjects of the invention are novel amine precursors and a novel process for manufacturing 5- ring heterocyclic amines.
