A fluorinated diamine intermediate

For the synthesis of polyimides in application of telecommunication and high-performance polymers


2,2-Bis[3-(4-aminobenzamido)-4-hydroxyphenyl]hexafluoropropane (CAS number 129197-38-2), known as p-6FDAP, has two terminal aminobenzamides linked to a bis(dihydroxyphenyl)hexafluoropropane. p-6FDAP is commonly used for synthesizing polyimides, especially those with low dielectric constant. A pedant group, such as biphenyl can be easily attached to the polymer backbone with the unreacted hydroxy groups. The molecular design is to obtain extra volume in bulk by the secondary relaxation behaviour of the polymers. Therefore, the dielectric constant of the grafted polyimides can reach 2.09 with dielectric loss of 0.0012 at 10 kHz. The grafted polyimides derived from p-6FDAP are ideal for telecommunication applications.

p-6FDAP based polyimides can be further functionalized by polymerizable groups, for instance acrylate, allowing they to be crosslinked for higher thermal resistance (5% decomposition temperature from 455 °C to 491 °C)
