Abstract:
Method for the preparation of polymers comprising contacting:at least one ethylenically unsaturated monomer, at least one source of free radicals, and at least one compound of the general formula (IA), (IB) or (IC): in which: R2 and R2, which may be identical or different, represent a group of the formula: in which: R3 and R4, which may be identical or different, are selected from a halogen group, â€”NO2, â€”SO3R, â€”NCO, CN, R, â€”OR, â€”SR, â€”NR2, â€”COOR, O2CR, â€”CONR2, â€”NCOR2, CnF(2n+1) with n being from 1 to 20, in which the groups R, which may be identical or different, represent H or a group selected from: alkyl, alkenyl, alkynyl, cycloalkenyl, cycloalkynyl, aryl, optionally fused to an aromatic or non-aromatic heterocycle, alkaryl, aralkyl, heteroaryl, which are optionally substituted by one or more identical or different groups selected from the group consisting of halogen, &boxH;O, &boxH;S, OH, alkoxy, SH, thioalkoxy, NH2, mono- or di-alkylamino, CN, COOH, ester, amide, CnF2n+1, and/or optionally interrupted by one or more atoms selected from the group consisting of O, S, N, and P, or a heterocyclic group optionally substituted by one or more groups such as defined above, or R3 and R4, together with the carbon atom to which they are attached, form a group &boxH;O, &boxH;S or a hydrocarbon ring or a heterocycle, R5 and R6, which may be identical or different, represent a group such as defined above for R, or R5 and R6 together form a C2-C4 hydrocarbon chain optionally interrupted by a hetero atom selected from O, S and N, R1 and R1â€², which may be identical or different, represent a group such as defined above for R3 or R4, p represents an integer from 2 to 10.
