摘　　要：Two series of pour point depressants(PPD) for crude oils were synthesis. One was acrylic acid esters (C\-\{18\} and C\-\{18-30\})-maleic anhydride copolymer aminolysed by successively reacting with C\-\{18\}-C\-\{30\} amine. The other was a maileic anhydride-alpha-olefins copolymer aminolysed by successively reacting with C\-\{18\}-C\-\{30\} amine. Adding 100ppm of PPD to Daqing crude oil combined with heat treating resulted a pour point depression of 19 to 22 ℃. When samples 100×10\+\{-6\} were added to Liaohe, Renqiu, Xinjiang, Daqing crude oil, results show that they have very good pour point depressing effects.Two series of pour point depressants(PPD) for crude oils were synthesis.
