Open publisher page 0 citations

Abstract

A series of 1.0-3.0G starburst polymer (PAMAM) was synthesized by divergence with ethylenediamine as core.The structure of PAMAM was characterized by IR,NMR and terminal group analysis,and the demulsification of PAMAM was investigated by using simulated water in oil emulsion. The results show that demulsification increases with increase of branch.At 50 ℃ with additive concentration of 150 mg/L,the demulsifying rate of 3 0 G PAMAM during 90 min reached 98 5% .
