Abstract: An emulsion breaker composition, a method of making the emulsion breaker, and method of breaking an emulsion are disclosed. In one method, an emulsion is contacted with an effective amount of an emulsion breaker composition. The emulsion breaker is a linear or branched polymer having at least one branch, wherein each branch has a first polymer block having a backbone including a plurality of ester groups and a second polymer block including an alkoxylate, and wherein at least two of the ester groups are connected by a - CR1R2 group. The emulsion breakers are preferably formed by reacting a polyol with a cyclic ester monomer in the presence of a first catalyst to form an intermediate polymer having a plurality of branches, wherein each branch has a backbone including a plurality of ester groups, and then reacting the intermediate polymer with at least one alkylene oxide species in the presence of a second catalyst to form an alkoxylate block on each branch.

Abstract translation: 公开了一种破乳剂组合物，一种制备该破乳剂的方法和一种破乳剂的方法。 在一种方法中，将乳液与有效量的破乳剂组合物接触。 破乳剂是具有至少一个支链的直链或支链聚合物，其中每个支链具有第一聚合物嵌段，其具有包含多个酯基的主链和包含烷氧基化物的第二聚合物嵌段，并且其中至少两个酯基 由 - CR1R2组连接。 乳液破乳剂优选通过在第一催化剂存在下使多元醇与环酯单体反应形成具有多个分支的中间体聚合物形成，其中每个分支具有包括多个酯基的主链，然后使 在第二催化剂存在下具有至少一种烯化氧物质的中间体聚合物，以在每个分支上形成烷氧基化物嵌段。
