ABSTRACT:
Cross-linked, synthetic polymer compositions comprising an aqueous polymer dispersion of (1) heterogeneous polymer particles having a high concentration of reactive groups such as an activated halogen on their surface and (2) a water-soluble coreactive component bearing a plurality of reactive groups coreactive with the reactive groups of the heterogeneous polymer particle, e.g., ##STR1## are useful for preparing strong films or coatings. For example, a polymer composition consisting of an aqueous colloidal dispersion of heterogeneous polymer particles having a shell layer derived from a reactive monomer such as vinylbenzyl chloride and a coreactive component of triethylenetetraamine can be applied to a suitable substrate and cross-linked to form a strong, water-resistant film.
