ABSTRACT:
A colloidal system is provided which is the emulsion polymerization product of an alkyl ester of acrylic or methacrylic acid where the alkyl portion of the ester substituent has from about 1 to about 18 carbon atoms; from about 0.5 to about 60 phm of acrylonitrile or substituted acrylonitrile; from about 0.005 to about 25 phm of a monocarboxylic or dicarboxylic acid; and optionally from about 0 to about 5 phm of a chain transfer agent. The latex system can be used to treat a fibrous substrate, and particular paper, to improve delamination and tensile characteristics.
