A procedure of preparation of amphoteric latex based copolymers of conjugated Dienes.

摘要

Process for the preparation of stable amphoteric latex based conjugated Dienes, by emulsion polymerization.Includes a First Stage consists in preparing an aqueous dispersion of particles in the presence anfotera putting at least one hydrolysable nitrogen saturated compound in acid or Alkaline medium, The reaction medium of operation in aqueous emulsion polymerization of at least one mo Not with that number ionogeno copolimerizable hydrolysable insoluble nitrogenous Compound.In a Second Stage copolimeriza within the aqueous dispersion anfotera obtained in the first stage, at least a conjugated Diene, in the presence of a cationic initiator or Generator loads.
