    • A thermally-responsive dispersant for an aqueous dispersion of positively- or negatively-charged or chargeable solid or liquid particulates, comprises a compound having an anchoring moiety linked to a thermally-responsive polymeric stabilizing moiety, other than a polyalkylene oxide, the polymeric moiety having a lower affinity for the surface than the anchoring group below the thermal transition temperature, the particulates being positively-charged or chargeable when the anchoring moiety contains an acid and/or hydroxy group and has a net acidity or neutrality and the particulates being negatively-charged or chargeable when the anchoring moiety has a basic group and has a net basicity, wherein the dispersion exhibits a change in sign from negative to positive and an increase in magnitude of a rheological property (viscosity at low shear and/or complex modulus at low amplitude oscillatory shear), on increasing the temperature from below to above the thermal transition temperature.
    • 用于带正电荷或带负电荷或带电荷的固体或液体颗粒的水性分散体的热响应性分散剂包括具有与热响应性聚合物稳定化部分连接的锚定部分的化合物,而不是聚环氧烷,所述聚合物部分具有 当锚定部分含有酸和/或羟基并且具有净酸度或中性并且颗粒带负电荷时,对于表面的亲和力低于锚定基团低于热转变温度的亲和力,所述颗粒被带正电或带电 或者当锚定部分具有碱性基团并且具有净碱度时可带电,其中分散体显示从负到正的变化和流变特性的大小(低剪切时的粘度和/或低振幅下的复数模量) 振荡剪切),将温度从低到高于热转变温度。
