摘　　要：在适宜的工艺条件下合成了支化代为0.5~2.0G的聚酰胺-胺型树枝状系列高分子（PAMAM）,并将2.0G PAMAM与环氧丙烷及环氧乙烷进行烷氧基化反应,制备了具有多分支结构的聚醚类破乳剂W-PAMAM。考察了整代PAMAM破乳剂和改性W-PAMAM破乳剂对水包油（O/W）型模拟原油乳液的破乳性能。实验结果表明,整代PAMAM破乳剂和改性W-PAMAM破乳剂均对O/W型模拟原油乳液有破乳作用,在温度为60℃、破乳时间为120 min、加量为100mg/L时,W-PAMAM对含油5%的O/W型模拟原油乳液的破乳除油率大于90%。A series of generation of 0. 5G to 2. 0G PAMAM are synthesized under the suitable conditions.Combinated with 2. 0G PAMAM and propylene oxide,ethylene oxide for the alkoxylation is taken to a reaction to get the polyether demulsifier（ W- PAMAM） with multi branch structure,which its demulsification perfermance is evaluated by using the simulation of crude oil emulsion（ O / W type）. The results show that the new type demulsifier added 100 × 10- 6at 60 ℃ and 120 min,can make 70% simulated emulsion of crude oil.
