| Abstract: | The main objective of this study is to synthesize lubricating oil viscosity index improvers(polystyrene-ethylene-propylene rubber SEP).Ethylene propylene monomer was chloridized,active polystyrene with different molecular and n-butyl lithium was synthesized,and graft polymer SEP was synthesized with anion coupled reaction.The molecular formation of Graft polymer was determined by GPC and NMR.The property of SEP was determined in lubricating oil viscosity index improvers.The result shows that SEP possesses p... |
