Abstract
A one-part, substantially formaldehyde-free, self-curing interpolymer comprising repeating units derived from a) about 4 to about 30 percent by weight of at least one functional monomer selected from olefinically unsaturated monomer containing a nucleophile group: b) about 4 to about 40 percent by weight of an olefinically unsaturated dicarboxylic acid; c) about 1 to about 60 percent by weight of (meth)acrylonitrile; d) about 0 to about 80 percent by weight of at least one monomer selected from the group consisting of (meth)acrylic acid ester of an alcohol containing 1 to 30 carbon atoms; and e) about 0 to about 80 percent by weight of at least one monomer selected from the group consisting of styrene, vinyl acetate, and vinyl halides, wherein at least one of monomers d) and e) are present in an amount of from about 0.1 percent by weight, for use as a fiber binder, such as for coating non-woven glass mats, or as a saturant for fiber substrates such as paper.
