titleOfInvention | Preparation method of C9 side chain substituted fluorine-containing diamine monomer |
abstract | The invention designs a polyimide diamine monomer C9-FBDA with an innovative structure, which realizes the simultaneous introduction of C9 side chain alkyl, trifluoromethyl, imide groups and a plurality of benzene ring structures in the molecular structure of the polyimide diamine monomer, breaks the regularity and crystallinity of polymer molecular chains, improves the free volume of a polymer, reduces the interaction among the molecular chains, and further greatly improves the film forming property and the optical transparency of polyimide. In the synthesis of the C9-FBDA, the invention develops an industrially applicable production process of the C9-FBDA, and the process has the advantages of short synthetic route, high yield, cheap and easily available raw materials, low production cost, simple and convenient operation, environmental friendliness, complete large-scale mass production and great industrial application value. |
