The Research of Acceleration of Span for Polyacrylates Condensation Reducer of Crude Oil

The poly octadecy acrylates, octadecyl acrylates-maleic anhydride-styrene copolymer (SL) condensa- tion reducers are synthesized by the medium of free radical polymerization, for the high condensation of high waxy crude oil.The structures of both are characterized by FT-IR and 1H-NMR.The impact of SPAN for the reduction of condensation result by SL is studied.Furthermore, the mechanism of composite condensation reducers is discussed.
