A process is presented for the preparation of a latex by the emulsion
polymerization at a temperature of between 30 and 90 C. of at least one
ethylenically unsaturated monomer in the presence of at least one
surfactant and of a seed of polymer particles with a diameter of between
200 and 450 nm. The seed particles represent from 5-25% by weight of the
total weight of the monomer and seed. The polymerization is initiated by a
mixed water-soluble/fat-soluble system. Also included are lattices
obtained from this process.
