WATER POLYMERE DISPERSIONS AND METHOD OF THEIER PRODUCTION

摘要

Aqueous polymer dispersions useful in coating corn positions comprise cationically, anionically or non-ionically stabilised particies in which the particles comprise (a) polymeric modifier as defined, (b) addition polymer, and (c) crosslinking agent, both (a) and (b) containing reactive groups and (c) containing complementary reactive groups. Preferably the dispersions are prepared by polymerising a solution of (a) and (c) in the monomer precursor of (b).
