    • A method for increasing a mean particle size of a 2-hydrocarbyl-3,3- bis(hydroxyaryl)phthalimidine is provided. The method comprises forming a mixture comprising a feedstream of the 2-hydrocarbyl-3,3-bis(4- hydroxyaryl)phthalimidine, and a solvent composition comprising an organic solvent and water, wherein the organic solvent is capable of at least partially dissolving the 2-hydrocarbyl-3,3- bis(hydroxyaryl)phthalimidine and forming an adduct with the 2-hydrocarbyl-3,3- bis(hydroxyaryl)phthalimidine. Then the mixture is heated at a temperature and for a time effective to decompose the adduct and form a 2-hydrocarbyl-3,3- bis(hydroxyaryl)phthalimidine product having a mean particle size greater than 5 microns. The 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidines with increased particle size are useful for producing polymers.
    • 提供了一种增加2-烃基-3,3-双(羟基芳基)苯并二氮吡啶的平均粒度的方法。 该方法包括形成包含2-烃基-3,3-双(4-羟基芳基)苯并嘧啶的进料流和包含有机溶剂和水的溶剂组合物的混合物,其中有机溶剂能够至少部分地将 (羟基芳基)苯并二氮吡啶,并与2-烃基-3,3-双(羟基芳基)苯并二氮吡啶形成加合物。 然后将混合物在有效分解加合物的温度下加热并形成平均粒度大于5微米的2-烃基-3,3-双(羟基芳基)苯并二氮嘧啶产物。 粒径增加的2-烃基-3,3-双(羟基芳基)苯二甲酰亚胺可用于生产聚合物。
