Abstract: Vinyl monomers are polymerized in the aqueous phase in the presence of at least one N-oxyl compound of a secondary amine, having no hydrogen atoms bonded to the alpha carbon atoms. This process substantially eliminates deposits on reactor surfaces.

Abstract: A method for polymerizing vinyl monomers in the aqueous phase. In order to avoid deposits from being formed on the surfaces of the reactor, polymerization occurs in the presence of at least one N-oxyl compound of a secondary amine carrying no hydrogen atoms on atoms alpha -C.
