摘　　要：针对高蜡原油的高凝点问题，通过自由基聚合得到了聚丙烯酸十八醇酯，丙烯酸十八醇酯-马来酸酐-苯乙烯共聚物（SL）降凝剂。借助红外光谱和^1H核磁共振谱图分析了产物的结构。考察了斯盘对SL降凝作用的影响，探讨了SL与斯盘复配的降凝机理。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.
