Abstract
A water soluble polymer or polymeric adduct has a backbone comprising a plurality of segments with amine functional groups and hydroxyl functional groups with a number average molecular weight of about 5.00 to 1,000,000 Daltons. The polymeric adduct may be formed as an addition product by reacting at least one multifunctional amine compound reacted with a one or more polyfunctional epoxy compounds and/or one or more monofunctional epoxy compounds, such that there are 1.3 to 3.8 reactive amine functional groups per reactive epoxy functional group. An aqueous solution of the polymer or polymeric adduct has a viscosity of about 100 centipoise to 100,000 centipoise and a pH value of about 8 to 12 when the solution comprises 70 wt. % of the polymer or polymeric adduct dissolved in water. The polymeric adducts are useful fast setting additives for emulsions due to excellent stability when blended with anionically stabilized latex.
