ABSTRACT:
The present invention provides a cationic latex of copolymers based on conjugated dienes, formed by the steps of preparing an aqueous dispersion of particles by reacting at least one unsaturated tertiary nitrogen compound not capable of being hydrolyzed in an acid or alkaline medium with an aqueous emulsion reaction medium, containing cationic species, of at least one non-ionic monomer capable of being copolymerized with the non-hydrolyzable unsaturated nitrogen compound to form synthetic polymers and at least one substance which generates cationic species capable of chemically binding with the synthetic polymers; the non-ionic monomer being converted to polymer in the reaction in a degree of up to at least about 30%; and polymerizing, in the aqueous dispersion, at least one conjugated diene or a mixture of conjugated dienes and at least one non-ionic monomer in the presence of an initiator selected from the group consisting of an uncharged initiator and a cationic charge-generating initiator.
