ABSTRACT:
This invention discloses a process for producing a polymer by controlled polymerization which comprises polymerizing at least one monomer in the presence of a free radical control agent of the structural formula: (Z)-(R1)n, wherein n represents an integer from 1 to about 6; wherein Z represents an aromatic or aliphatic moiety containing from 1 to about 20 carbon atoms; wherein R1represents a moiety of the structural formula:wherein R2represents a moiety selected from the group consisting of alkyl groups, alkenyl groups, alkynyl groups, aryl groups, heteroaryl groups, and alkaryl groups; wherein the alky groups, alkenyl groups, alkynyl groups, aryl groups, heteroaryl groups, and alkaryl groups can be substituted, unsubstituted, linear, branched or cyclic; and wherein Ar represents a p-alkoxyphenyl group having an alkoxy moiety that contains from 1 to 8 carbon atoms.
