The invention relates to a binary polymer diesel pour point depressant as well as a preparation method and application thereof.Methacrylic acid higher alcohol ester and 1, 2, 3, 6-tetrahydrophthalic anhydride are subjected to a polymerization reaction under the action of an initiator to prepare a methacrylic acid higher alcohol ester-1, 2, 3, 6-tetrahydrophthalic anhydride binary polymer, namely the binary polymer diesel pour point depressant. Compared with the prior art, the binary polymer diesel oil pour point depressant prepared by the preparation method disclosed by the invention not only has relatively strong oil solubility, but also can effectively improve the low-temperature flowing property of diesel oil, has a good effect in the aspect of reducing a condensation point and a cold filter plugging point, and provides a new possibility for research and development of a novel diesel oil pour point depressant. 本发明涉及一种二元聚合物柴油降凝剂及制备方法与应用，本发明将甲基丙烯酸高碳醇酯与1,2,3,6-四氢苯酐，在引发剂作用下，经聚合反应制得甲基丙烯酸高碳醇酯-1,2,3,6-四氢苯酐二元聚合物，即
