| titleOfInvention | Free radical polymerisation process |
| abstract | Process for the free-radical polymerisation of olefinically unsaturated monomer(s) using a free-radical initiator, wherein said polymerisation is performed in the presence of a compound for effecting molecular weight control, said molecular weight control compound being selected from Cobalt II chelates of formulae (I), (II) and (III), wherein: x and y are independently 2 to 5; each R?1, R2, R3 and R4¿ is independently selected from H, C1-C12 alkyl, optionally substituted aryl, OR5 where R5 is C1 to C12 alkyl or optionally substituted aryl, CO¿2R?5, SO3H, C(=O)R5, CO2H, NO2, OH, NR52, NH2, NHR5, SR5, SH, CN, SO¿3R?5, halogen, 2-furyl and 3-furyl; each X is independently selected from (CR62)n, (CR62O)n, optionally substituted o-phenylene, and optionally substituted 1,8-naphthylene, where each R6 is independently selected from H and C1 to C12 alkyl, and n is 1 to 10; and wherein said cobalt chelates of formulae (I) and (II) possess a positive charge of 2 and are associated with an anion or anions for balancing the positive charge, while that of formula (III) is neutral; and also Co III analogues of said cobalt (II) chelates of formulae (I), (II) and (III) in which the Co atom is additionally covalently bonded, in a direction at right angles to the macrocyclic chelate ring system, to H, a halide ion or other anion, or a homolytically dissociatable organic group. |
