Özet

Copper-catalyzed living radical polymerization (LRP) of styrene was carried out in the presence of fructose as a reducing agent for Cu(II) by using either 1-chloro-1-phenyl ethane (1-PECI), ethyl-2-bromoisobutyrate (EiBr) or methyl-2-bromopropi on ate (MBP) as an initiator and N, N, N',N '',N ''-pentamethyldiethylenetriamine (PMDETA) as ligand at 110 degrees C. Kinetic experiments were carried out in order to reveal the effect of fructose concentration on copper-catalyzed LRP of St. This technique was successfully applied for the preparation of homo-polymers (linear and star-type polystyrene (PS)) and corresponding block co-polymers (PS-b-PMMA). The polymers thus obtained were characterized using GPC, H-1-NMR and MALDI-TOF measurements.
