    Abstract: A vinyl polymer pigment dispersing agent having a vinyl addition polymer backbone, one or more polymer side chains with pendant cyclic urea functional group(s) separated from the polymer backbone by at least 10 intervening atoms, and in some embodiments one or more polymer side chains comprising pendant urea functional groups separated from the polymer back-bone by less than 10 intervening atoms. The dispersing agent may be made by addition polymerizing a mixture of one or more vinyl monomers and one or more monomers having cyclic urea functional groups and vinyl functional groups. The dispersing agent may be combined with pigment particles, a carrier and an optional surfactant to make a pigment grind dispersion with excellent pigment wetting and dispersing properties.

    Abstract translation: 一种乙烯基聚合物颜料分散剂,其具有乙烯基加成聚合物主链,一个或多个具有侧链环脲官能团的聚合物侧链通过至少10个中间原子与聚合物主链分离,并且在一些实施方案中为一个或多个聚合物侧链 包括从聚合物背骨分离少于10个中间原子的侧链脲官能团。 分散剂可以通过加成聚合一种或多种乙烯基单体和一种或多种具有环状脲官能团和乙烯基官能团的单体的混合物来制备。 分散剂可以与颜料颗粒,载体和任选的表面活性剂组合以制备具有优异的颜料润湿和分散性能的颜料研磨分散体。
