Process for the preparation of a graft copolymer latex of core/shell dispersion particles having improved phase binding between core and shell

摘要

The invention relates to the preparation of a graft copolymer latex of core/shell dispersion particles having improved phase binding between core and shell in a two-stage emulsion polymerization process, hydroperoxide groups being produced at the particle surface of the grafting base prior to grafting by hydrogen peroxide treatment.
