Abstract: Graft copolymers are obtained by an aqueous- phase process in which polymerization of the rubber-elastic base is taken to completion and an N-oxyl radical compound of a sec. amine with no hydrogens on the alpha -carbon atom is added before and/or during polymerization of the grafted shell. A process for the production, in the aqueous phase, of graft copolymers (A) of (a1) 30-95 wt% rubber-elastic graft base derived from (a11) 50-100 wt% conjugated diene and (a12) 0-50 wt% other monounsaturated monomer(s) or from (a11 asterisk ) 50-100 wt% 1-10C alkyl acrylate, (a12 asterisk ) 0-10 wt% polyfunctional crosslinking monomer and (a13 asterisk ) 0-40 wt% other monounsaturated monomer(s) and (a2) 5-70 wt% grafted shell derived from (a21) 50-100 wt% styrene compound of formula (S): R , R = H or 1-8 C alkyl (a22) 0-40 wt% (meth)acrylonitrile and (a23) 0-40 wt% other monounsaturated monomer(s). In this process, polymerization of the base stage (a1) is taken to completion and then at least one N-oxyl radical compound of a sec. amine with no hydrogen atoms on the alpha -carbon atom is added before and/or during polymerization stage (a2).

Abstract: A method of radical-initiated emulsion polymerisation for the production of aqueous polymer dispersions comprises emulsifying unsaturated monomer(s) in aqueous media with the aid of dispersants and then polymerising with a radical initiator in presence of a stable N-oxyl radical, at above 100 deg C and at a pressure above the vapour pressure of the reaction mixture. The initiators used comprise peroxides, hydroperoxides and/or azo compounds with a molal solubility at 25 deg C and 1 bar in water which is greater than or equal to that of tert.-butyl hydroperoxide and with a dissociation temperature of less than 100 deg C in the polymerisation mixture. Also claimed are aqueous polymer dispersions obtained by this process.
