摘要： The residual chlorine content of a polyolefin-substituted carboxylic acylating agent formed by a halogen-assisted reaction of a polyalkene and at least one olefinic, monounsaturated mono- or dicarboxylic acid, anhydride or ester, is reduced when the reaction is conducted in the presence of a controlled amount of a metal compound.

摘要翻译： 通过聚烯烃和至少一种烯属单不饱和单羧酸或二羧酸酐或酯的卤素辅助反应形成的聚烯烃取代的羧酸酰化剂的残留氯含量在反应在 受控量的金属化合物。
