Abstract:

A novel bisphenol F-type dianhydride(BPFDA) monomer was synthesized using 4-chlorophthalimide through hydration, acidification, and dehydration. Its structure was determined with 1H NMR and IR. Two types of polyimide films were prepared with the dianhydride and 4,4′-diaminodiphenyl ether(ODA) or 4,4′-methylene dianiline(MDA) via conventional one-step method in N,N′-dimethylacetamide. The obtained polyamic acid was then further imidized into polyimide films and characterized. Results show that the glass-transition temperatures of the polyimide films were 200 and 204 ℃;the temperatures of 5% mass loss were 506.50 and 459.10 ℃; and the tensile strength of the films were 110 and 100 MPa, respectively.

Key words: BPFDA, Polyimide, Thermal property, Mechanical properties.
