Abstract The Synthesis of mixed alcohols esterified copolymer of maleic anhydride with acrylic alkyl ester, olefins and styrene(MOAS) as pour-point depressant (PPD) for diesels was introduced. By using the synthesized MOAS, the pour-point (PP) and cold filter plugging point (CFPP) of the tested diesels made from Daqing crude oils were lowered obviously as those did by other PPDs. Meanwhile the machanism of its function was investigated.
