Abstract

A process for the production of latex from conjugated diene polymers and copolymers of conjugated diene with vinyl compounds, with low viscosity, high solids content and large and uniform particle sizes that do not show gel formation, by emulsion polymerization in the that the monomers are added together with a chain regulator and an emulsifier to the aqueous reaction medium containing a polymerization catalyst and a dispersing agent, the process of which is characterized by: (a) carrying out a first polymerization phase in the presence of the monomer as a phase other than the polymer being formed; (b) performing an intermediate phase in which the monomer is added in amounts such that the conversion of the monomer at the end of each individual addition is greater than 45% and (c) carry out a final phase in which the reaction is completed.
