    • A process for producing polyalkenyl acylating agent, wherein, upon completion of the thermal reaction of a polyalkene and an unsaturated mono- or dicarboxylic acid or anhydride compound, the reaction mixture is allowed to cool to below the reaction temperature, an additional amount of unsaturated mono- or dicarboxylic acid or anhydride compound is added to the cooled reaction mixture, which is then maintained in the reactor for a time period, optionally with agitation. Reducing the temperature of the reaction mixture prior to the introduction of additional unsaturated mono- or dicarboxylic acid or anhydride compound minimizes further reaction between the additional unsaturated mono- or dicarboxylic acid or anhydride compound and any remaining unreacted polyalkene, as well as self-polymerization of the unsaturated mono- or dicarboxylic acid or anhydride compound. Polymerized unsaturated mono- or dicarboxylic acid or anhydride compound in the reactor, suspended in the reaction mixture in the form of sediment or deposited on the internal walls of the reactor vessel as tar, is dissolved by the additional unsaturated mono- or dicarboxylic acid or anhydride compound and removed from the reactor upon draining of the reactor vessel.
    • 一种生产聚烯酰化剂,worin,在不饱和单或二羧酸或酸酐化合物的一种聚烯烃和热反应完成后处理,将反应混合物冷却至低于反应温度,在不饱和单的额外量 - 或二羧酸或酸酐化合物加入到冷却的反应混合物,在所有其然后保持在反应器中的时间段,任选地搅拌。 减少在引入额外的不饱和单或二羧酸或酸酐化合物的反应混合物的温度最小化的附加不饱和单或二羧酸或酸酐化合物和任何剩余的未反应的聚烯烃之间的进一步反应,以及自聚合 的不饱和单或二羧酸或酸酐化合物。 在反应器中聚合的不饱和单或二羧酸或酸酐的化合物,悬浮在沉降物的形式的反应混合物或沉积在反应器容器如焦油的内壁上,通过附加不饱和单或二羧酸或酸酐溶解 化合物和在所述反应器容器的排出从反应器中除去。
