The bis phenyl 2,3,5,6 tetrafluoro 4 trifluoromethyl phenyl phosphine oxide derivative and to its production mannered

摘要

PROBLEM TO BE SOLVED: To provide a bisphenyl-2,3,5,6-tetrafluoro-4-trifluoromethylphenylphosphine oxide derivative, and to provide a method for producing the same.;SOLUTION: This bisphenyl-2,3,5,6-tetrafluoro-4-trifluoromethylphenylphosphine oxide derivative comprises a new substance having such a structure that a perfluorinated benzene substituent and phosphine oxide are substituted in its molecule at the same time, wherein the derivative is useful as a monomer for being polymerized into a polyimide which does not only keep excellent thermal/mechanical characteristics inherent in the polyimide, but also has a low dielectric constant and excellent adhesion. Further, the method for producing the same is provided.;COPYRIGHT: (C)2006,JPO&NCIPI
