  • Publication number: 20050131178
    Abstract: A controlled free radical polymerization process, which includes the steps of: adding a monofunctional iniferter compound to an oxygen-free solvent; heating the solution to a temperature sufficient to allow the iniferter compound to form two carbon centered radical residues; adding a first monomer composition comprising one or more monomers to the solution containing the radical containing residues; polymerizing the first monomer composition to form a quasi-living polymer; and optionally polymerizing a second monomer composition comprising one or more monomers, which are different than the first monomer composition. The resulting non-random copolymer having the general formula: ?-[-Ap-Bs-]t-? where A and B are different compositions of ethylenically unsaturated monomers; p is an integer from 1 to 1,000; s is an integer from 0 to 1,000; t is an integer from 1 to 100; and ? is a residue from the iniferter.
