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.
水溶性聚合物或聚合物加合物的骨架由多个具有胺官能团和羟基官能团的区段组成,其平均分子量约为 5.00 至 1,000,000 道尔顿。聚合物加合物可通过至少一种多官能胺化合物与一种或多种多官能环氧化合物和/或一种或多种单官能环氧化合物反应形成加成产物,从而使每个反应性环氧官能团具有 1.3 至 3.8 个反应性胺官能团。聚合物或聚合物加合物水溶液的粘度约为 100 厘泊至 100,000 厘泊,pH 值约为 8 至 12(当溶液中溶解有 70 重量百分比的聚合物或聚合物加合物时)。聚合物加合物与阴离子稳定胶乳混合后具有极佳的稳定性,因此可作为乳液的快速固化添加剂。
