Abstract:
A polymerizable composition, comprisinga) at least one ethylenically unsaturated monomer or oligomer, and b) a compound of formula (I) â€ƒin which n is the number 1 or 2, and R1 is a group of the formula â€ƒin which G1 and G2 are hydrogen, methyl or, together, are a substituent &boxH;O, E is â€”Oâ€” or â€”ND3â€”, A is C2-C6alkylene or â€”(CH2)3â€”Oâ€” and x1 is the number 0 or 1, D3 is hydrogen, C1-C12alkyl, C2-C5hydroxyalkyl or C5-C7cycloalkyl, R2 is identical to R1 or is one of the groups â€”N(G21)(G22), â€”OG23, â€”N(H)(CH2OG23) or â€”N(CH2OG23)2, R3, if n=1, is identical to R1 and, if n=2, is an â€”Eâ€”D4â€”Eâ€” group, in which D4 is C2-C8alkylene or C2-C8alkylene which is interrupted by 1 or 2 â€”NG21â€” groups, G21 is C1-C12alkyl, cyclohexyl, benzyl or C1-C4-hydroxyalkyl or a group of the formula G22 is C1-C12alkyl, cyclohexyl, benzyl or C1-C4hydroxyalkyl, and G23 is hydrogen, C1-C12alkyl or phenyl, or G21 and G22 together are C4-C5alkylene or C4-C5oxaalkylene, for example â€”CH2CH2â€”Oâ€”CH2CH2â€”, or a group of the formula â€”CH2CH2â€”N(G11)â€”CH2CH2â€”; and G11 is OÂ· or â€”Oâ€”X, wherein X represents a group selected from the group consisting of â€”CH(aryl)2, â€”CH2-aryl, â€ƒâ€”CH2â€”CH2-aryl, â€ƒ(C5-C6cycloalkyl)2CCN, (C1-C12alkyl)2CCN, â€”CH2CH&boxH;CH2, (C1-C12)alkyl-CR30â€”C(O)â€”(C1-C12)alkyl, (C1-C12)alkyl-CR30â€”C(O)â€”(C6-C10)aryl, (C1-C12)alkyl-CR30â€”C(O)â€”(C1-C12)alkoxy, (C1-C12)alkyl-CR30â€”C(O)-phenoxy, (C1-C12)alkyl-CR30â€”C(O)â€”N-di(C1-C12)alkyl, (C1-C12)alkyl-CR30â€”COâ€”NH(C1-C12)alkyl, (C1-C12)alkyl-CR30â€”COâ€”NH2, â€”CH2CH&boxH;CHâ€”CH3, â€”CH2â€”C(CH3)&boxH;CH2, â€”CH2â€”CH&boxH;CH-phenyl, â€ƒâ€”Oâ€”C(O)â€”C1-C12alkyl, â€”Oâ€”C(O)â€”(C6-C10)aryl, (C1-C12)alkyl-CR30â€”CN, â€ƒwherein R30 is hydrogen or C1-C12alkyl; the aryl groups are unsubstituted or substituted with C1-C12alkyl, halogen, C1-C12alkoxy, C1-C12alkylcarbonyl, glycidyloxy, OH, â€”COOH or â€”COOC1-C12alkyl such that the free radical XÂ· derived from X is an initiator of polymerization of ethylenically unsaturated monomers at a temperature of between 50Â° C. and 180Â° C.; and if G11 is OÂ·, a source of free radicals is additionally present.
