Zusammenfassung:	This efficient pour depressant used for high-set-point crude oil and oil products is made up through the esterification of caopolymer of maleic anhydride and mixed alpha-olefin by primary alcohol whose number of carbon atons is 8-40 (18 is recommended) to obtain a mixed esterified matter and addition of aromatic hydrocarbon solvent whose quantity is twice as that of the former. Combined with 70 deg. C thermal treatment, 0.5-1.0% such pour depressant is added in Daqing crude oil to lower its set point from 23 deg. C when single thermal treatment to 15-13 deg. C. If 1.0% such pour depressant is added in heavy diesel oil at 50 deg. C, its set point may be lowered from 16 to 3 deg. C.
