摘要
Abstract
Mesodyn simulation was used to study the solution property and the distribution on oil-water interface of polymeric macromolecular surfactant(PMS)with functional side chains as ethylene oxide(EO)and propylene oxide(PO)and different distribution structure of side chain.The simulation results show that when the EO side chains and PO side chains are distributed on each side of the main chain of PMS separately,the arrangement of PMS at the oil-water interface is more orderly,proving better interface performance.When the EO side chain and PO side chain are located on the same side of the main chain of PMS,the ordered arrangement of PMS at the oil-water interface is relatively low,and the interface performance of PMS is weak.With same length of functional side chains,the associations of hydrophilic functional side chains and the viscosity enhancement properties of PMS have little relationship with the structure of functional side chains.关键词
