| description | Telechelic polymers are prepared using a functionalization reagent containing the desired functional groups. A process for the production of telechelic polymers (I) of formula (1) comprises polymerization of (A) radically polymerizable, ethylenically unsaturated monomers of formula (2); (B) an initiator compound; (C) a transition metal compound; and (D) complex ligands that complex to the central atom of (C); in the presence of (E) a functionalization reagent containing at least a carbon-carbon double bond and functional groups Y , Y . Q = an oligomeric hydrocarbon, optionally substituted having a molecular weight of 300-10000 and of formula -(CHR'-CR''R''')n- (3); n = 3-500; R', R'', R''' = H, 1-20C (cyclo)alkyl, 6-24C aryl, halogen, CN, 1-20C alkylester or amide, 6-24C arylester or amide and optionally contain functional groups such as aldehyde, ketone or ether groups, R' and R'' may also be components of a ring, preferably a cyclic anhydride, imide or alkane; and Y , Y = functional groups. An Independent claim is also included for the resulting (telechele). |
