  Polybutenyl substituted succinic acylating agents are formed by reacting (a) an acidic reactant represented by the general formulaR - CO - CH = CH - CO - R′ wherein R and R′ are independently -OH, -O-lower alkyl, a halogen atom, or taken together are a single oxygen atom, with (b) a polymer composed mainly or entirely of polyisobutene, at least 50% of the polyisobutene content of the polymer having an end group represented by the formula The mole ratio of acidic reactant : polymer is at least 1 : 1; and the reaction mixture is maintained under superatmospheric pressure during at least a substantial portion of the reaction period. The reaction rate is high, the yields of desired product are high, and despite the fact that superatmospheric pressures and elevated temperatures are used, the process forms only small amounts of tars or resinous co-products, even when employing as much as a 20% or more molar excess of maleic anhydride. Any unreacted acidic reactant such as maleic anhydride, maleic acid, fumaric acid, etc. can be, and preferably is, recovered from the reaction mixture, and thus is available for use either as recycle to the process or for other uses. Inasmuch as chlorine is not used in the process, the expense and difficulties associated with handling chlorine on a plant scale are eliminated, and the product is less corrosive than corresponding products formed by use of chlorine.

  聚丁烯基取代的琥珀酰化剂是通过以下反应形成的：(a) 由通式 R - CO - CH = CH - CO - R′表示的酸性反应剂，其中 R 和 R′独立地为-OH、-O-低级烷基、卤素原子或合在一起为单个氧原子；(b) 主要或全部由聚异丁烯组成的聚合物，聚合物中至少 50%的聚异丁烯含量具有由式表示的末端基团 酸性反应剂与聚合物的摩尔比至少为 1:1；反应混合物在至少大部分反应期间保持在超大气压下。尽管使用了超大气压和高温，但反应速率很高，所需产物的产量也很高，即使马来酸酐的摩尔过量高达 20% 或更多，该工艺也只形成少量焦油或树脂状副产品。任何未反应的酸性反应物，如马来酸酐、马来酸、富马酸等，都可以而且最好是从反应混合物中回收，从而可用于工艺的循环或其他用途。由于工艺中不使用氯，因此消除了工厂处理氯的费用和困难，而且产品的腐蚀性低于使用氯形成的相应产品。
