Process for the preparation of polymer particles possessing, implanted on their surface, amphophilic molecules carrying ion-forming or reactive groups, and a process for the preparation of a latex comprising these particles

摘要

Polymer particles possessing, implanted on their surface, amphiphilic molecules carrying ion-forming or reactive groups, and dispersions thereof, prepared by diffusing, into a previously prepared aqueous seeding dispersion of polymer particles, an organosoluble polymerization initiator, swelling the particles of the dispersion thus obtained by introducing a monomer composition comprising at least one monomer and at least one amphiphilic compound, and polymerizing the monomer composition.
