Water-resistant films and coatings based on cross-linking styrene-acrylatelatex copolymers

Water-resistant films and coatings were prepared from latexes of copolymers of styrene, n-butyl acrylate, 2-hydroxyethyl methacrylate, glycidyl methac rylate, and methacrylic acid. The degree of crosslinking of the copolymers in the course of film formation and the water resistance of the films and c oatings, associated with this parameter and evaluated by the water absorpti on and mechanical properties of wet films, were studied in relation to the gross composition of the latex copolymer, conditions of its synthesis, dist ribution of functional groups responsible for cross-linking in a latex part icle, and temperature of film formation.
