ABSTRACT:
A self-crosslinking polymer consisting essentially of at least 1 mole % of a halohydrin monomer, at least 1 mole % of a tertiary or secondary amine salt monomer, and 0-98 mole % of a vinyl polymerizable monomer other than the halohydrin or amine salt monomers crosslinks, in the presence of a base, at a lower temperature than a polymer without the tertiary or secondary amine salt monomer. Typical polymers contain 3-chloro-2-hydroxypropyl acrylate or methacrylate; diallylamine hydrochloride, N-isopropyl methacrylamide hydrogen sulfate, dimethylaminopropyl methacrylamide, or dimethylaminoethyl methacrylate hydrochloride or acetate; and optionally other monomers such as a vinyl ester, an acrylate, or a dialkyl diallyl ammonium chloride. When the polymers contain a conductive cationic monomer such as dimethyl diallyl ammonium chloride, they are useful as electroconductive coatings for paper substrates. An adduct of epichlorohydrin and dimethylaminopropyl methacrylamide or dimethylaminoethyl methacrylate may be used in place of the 3-chloro-2-hydrodxypropyl acrylate or methacrylate for the electroconductive coatings.
