    Abstract: A preparation method of a polyester particle dispersion includes: under predetermined depolymerization conditions, mixing a polyester binder resin, a resin dissolvent and a polycondensation catalyst to depolymerize the polyester resin and form a first reaction mixture; adding a first monomer to the first reaction mixture to form a second reaction mixture; under predetermined polymerization conditions, adding a second monomer to the second reaction mixture to polymerize the depolymerized polyester resin and form a third reaction mixture; adding a neutralizing agent to neutralize the polymerized reaction product of the third reaction mixture; (e) adding a reverse-neutralizing agent to reverse neutralize the neutralized mixture; and adding a mixture of an anionic surfactant and a nonionic surfactant to the reverse-neutralized mixture.

    Abstract translation: 聚酯颗粒分散体的制备方法包括：在预定的解聚条件下，将聚酯粘合剂树脂，树脂溶剂和缩聚催化剂混合以使聚酯树脂解聚并形成第一反应混合物; 向第一反应混合物中加入第一单体以形成第二反应混合物; 在预定的聚合条件下，向第二反应混合物中加入第二单体以聚合解聚的聚酯树脂并形成第三反应混合物; 加入中和剂以中和第三反应混合物的聚合反应产物; （e）加入反中和剂反向中和中和的混合物; 并将阴离子表面活性剂和非离子表面活性剂的混合物加入到逆中和的混合物中。
