    • The present disclosure provides methods for modifying polymeric resin materials after polymerization to make fine adjustments in the chemical or physical properties of the resin, or in modifying the structure of the polymer chains. The resulting resins may be useful in forming toner particles. In embodiments, a polymeric resin may have epoxy groups added to its backbone to increase its melting point. The resulting polymer, sometimes referred to herein as an epoxidized polymer, may, in turn, be reacted with wax-like components, to increase the compatibility of the polyester with waxes utilized in forming toner particles. In other embodiments, the resulting epoxidized polymer may be reacted with components possessing carboxylic acid groups to adjust the acid value and weight average molecular weight of the resin.
    • 本公开提供了在聚合后改性聚合物树脂材料以对树脂的化学或物理性能进行微调或在改变聚合物链的结构的方法。 得到的树脂可用于形成调色剂颗粒。 在实施方案中,聚合物树脂可具有加成其主链的环氧基团以增加其熔点。 所得聚合物,有时在本文中称为环氧化聚合物,可以进一步与蜡状组分反应,以增加聚酯与形成调色剂颗粒中所用蜡的相容性。 在其它实施方案中,所得到的环氧化聚合物可以与具有羧酸基团的组分反应,以调节树脂的酸值和重均分子量。
