Process for preparing telechelic polymers, also prepared telechelic polymers and their use

Die Erfindung betrifft ein neues Verfahren zur Herstellung von oligomeren und polymeren Telechelen, die so hergestellten Telechele sowie ihre Verwendung im Kunststoff-, Faser- oder Lackbereich. 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).
