Abstract:
A polymerizable composition, comprisinga) at least one compound of formula (I) (RG)â€”Aâ€”(Stab)â€ƒâ€ƒ(I) â€ƒwherein (Stab) is a light stabilizer radical selected from the group consisting of sterically hindered amines, hydroxyphenyl-s-triazines, hydroxyphenyl-benzotriazols and o-hydroxy-benzophenones; A is a spacer group or a direct bond; and (RG) is a group containing at least one ethylenically unsaturated functional group; and a compound selected from the group consisting of b1) a compound of formula (II) Yâ€”Xâ€ƒâ€ƒ(II) â€ƒwhich contains a structural element>Nâ€”Oâ€”X where the nitrogen atom is part of a cyclic ring system or is substituted to form an acyclic structure, and wherein X represents a group having at least one carbon atom and is such that the free radical derived from X is capable of initiating polymerization; and a compound selected from the group consisting of b2) a stable free radical having a structural element>Nâ€”OÂ· where the nitrogen atom is part of a cyclic ring system or is substituted to form an acyclic structure and a free radical source from which a radical is formed capable of initiating polymerization;b3) a compound of formula (III) â€ƒand a catalytically effective amount of an oxidizable transition metal complex catalyst where the transition metal is present as a transition metal complex ion in the lower oxidation state of a redox system; â€ƒwherein [In] represents a polymerization initiator fragment of a polymerization initiator of formula (III) capable of initiating polymerization of monomers or oligomers, which polymerization initiator is selected from the group consisting of C1-C8-alkyl halides, C6-C15-aralkylhalides, C2-C8&agr;-haloalkyl esters, arene sulfonyl chlorides, haloalkanenitriles, &agr;-haloacrylates and halolactones; p and q represent one; and -[Hal] represents a leaving group; and optionallyc) one or more ethylenically unsaturated monomers or oligomers different from those of formula (I).
