Zusammenfassung:	The invention relates to a polymethacrylate-vinyl acetate diesel pour point depressant as well as preparation and application thereof. The preparation method of the diesel pour point depressant comprises the following steps: 1) adding methacrylic acid, higher alcohol and a polymerization inhibitor into a solvent, heating the components to 55-65 DEG C to be fully dissolved, then adding a catalyst,and carrying out a catalytic reaction to obtain methacrylic acid high-carbon ester; and 2) adding high-carbon methacrylate and vinyl acetate into a solvent, then adding an initiator, and carrying outa polymerization reaction to obtain a high-carbon methacrylate-vinyl acetate binary polymer, i.e., the polymethacrylate-vinyl acetate diesel pour point depressant. Compared with the prior art, the polymethacrylate-vinyl acetate diesel oil pour point depressant solves the problem that a single methacrylic acid pour point depressant is poor in broad spectrum, wherein the composition of the pour point depressant is expanded b
