Abstract:
A process for producing a vinyl polymer from a vinyl monomer by radical polymerization, said process comprising the step of:including in the polymerization system a hydroxylamine represented by a general formula (1): ##STR5##wherein in formula (1), R.sub.1 and R.sub.2 independently are selected from the group consisting of hydrogen, substituted aliphatic hydrocarbon groups having one or more carbon atoms and aromatic hydrocarbon groups;and/or general formula (2): ##STR6##wherein in formula (2), R.sub.3 and R.sub.4 independently are substituted aliphatic hydrocarbon groups having one or more carbon atoms;wherein the radical polymerization is carried out by any mode selected from the group consisting of bulk polymerization, suspension polymerization, and solution polymerization.
