Abstract

A process for preparing polymers of N-vinyl compounds comprises polymerizing the vinyl compounds in the presence of free radicals of the formula I where Q is NR2 or S and T is CR3R4 or S and R1, R2, R3 and R4 can be identical or different and are, independently of one another, hydrogen, C1-C20-alkyl or C6-C18-aryl.
