The invention discloses a polymethyl ethylene carbonate modification method, a modified material and application thereof. The modification method comprises the following steps of: mixing polymethyl ethylene carbonate with a modifying agent; and fusing and melting at 110-140 DEG C to obtain a modified material of the polymethyl ethylene carbonate, wherein the modifying agent comprises one or more of polyethylene, a polyolefin plastomer, a polyolefin elastomer, an ethylene-vinyl acetate copolymer, an ethylene acrylic acid copolymer, a maleic anhydride grafted polyethylene and a maleic anhydride grafted ethylene-octylene copolymer. The polymethyl ethylene carbonate modification method provided by the invention is simple in process, easy to control and low in cost; the modified material is free of peculiar smell, can be used as a middle partition layer with excellent performance, can be used for preparing a cosmetic hose, is capable of greatly broadening the application of a carbon dioxide-based copolymer, high i
