Abstract

N-vinyl lactams are polymerized to give polymers having a Fikentscher K value of 20 to 40 using an azo catalyst and employing a hydroperoxide as a chain transfer agent. The polymerization is carried out in solution and the solvent is either water or a lower aliphatic alcohol. The preferred hydroperoxide is hydrogen peroxide.
