The invention provides a convenient and high-efficient method for compounding synthetic trifluorovinyl aryl ether compound and an application thereof. Particularly, the invention provides a trifluorovinyl aryl ether compound with formula Ia structure and a trifluorovinyl aryl ether structure unit with formula Ib structure, and an application thereof; definition of every radical in the formula is the same as the description in a specification. The preparation method of the Ia and Ib structural compounds include steps of removing aryl trifluorovinyl ester, and thereby forming the trifluorovinyl aryl ether compound. Ar-(OCF=CF2)n(Ia)-Ar-(OCF=CF2)N(Ib).
