Atom transfer radical polymerization (ATRP) is one of the most successful methods to polymerize styrenes, (meth)acrylates and a variety of other monomers in a controlled fashion. Novel ligands, 4-alkyl pyridine-2-carboxamides(R = methyl (1a), butyl(1b)), have been prepared by the reaction of 4-alkyl-2-cyanopyridine with water in the presence of 0.4 mol% base in ethanol solution. The living free radical polymerization of 1,3-butadiene has been shown to be a facile process in the presence CuBr/ 1a catalytic system. Several effects, such as ligand, solvent, temperature and kinetic study of homopolymerization of 1,3-butadiene have been studied systematically. |
