Latex compositions with improved water resistance, chemical stability and rheological properties, useful either as the sole binder or as the co-binding agent with pigmentary material in paper coating compositions, made by aqueous emulsion polymerization of a monomeric mixture of, by weight, A. 35 to 75 parts of a monovinylidene aromatic monomer (e.g., styrene), B. correspondingly 65 to 25 parts of an aliphatic conjugated diene, said monomers (A) plus (B) constituting from 75 to 99.5% of the total monomeric mixture, C. 0.5 to 10% of an acryloyloxycarboxylic acid type monomer (e.g., beta-carboxyethylacrylate), and, optionally, D. 0 to 15% of one or more different hydrophilic monomers (e.g., mono-beta-hydroxyethylmaleate). |
