Abstract: A process of preparing an aqueous solution of a cycloimide-containing polymer includes heating an aqueous solution of a cycloanhydride-containing polymer with a first neutralizing agent at a ratio of cycloanhydride to neutralizing agent of about 1:1 to about 1:1.5 at a temperature and for a time sufficient to form the aqueous solution of the cycloimide-containing polymer having a cycloimide to acid group ratio of about 1:2 to about 1.5:2.

Abstract: Described herein is a multi-phase polymer binder including an aqueous polymer dispersion, an optional hydrophobic emulsion, and an optional surfactant. The polymer binder, when dried, provides a water uptake of less than about 5 g/m2/20 min, a seal strength of at least about 200 Newton/meter (N/m) as measured at 25° C. or at 90° C., and sufficient block resistance to impart no substrate damage.
