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.
