Abstract

A novel diamine monomer, containing fluorine and phosphine oxide, bis(3-aminophenyl) 3,5-bis(trifluoromethyl) phenyl phosphine oxide (mDA6FPPO), was prepared via Grignard reaction, and utilized to prepare polyimides with dianhydrides such as PMDA, 6FDA, BTDA or ODPA, by the conventional two-step route; preparation of poly(amic acid), followed by solution imidization. The polyimides were characterized by FT-lR, NMR, DSC and DMA, with intrinsic viscosity, and adhesive properties were also evaluated. A phosphine oxide containing monomer, bis(3-aminophenyl) phenyl phosphine oxide (mDAPPO) a nd a commercial 3,3'-diamino diphenyl sulfone (mDDS) were also used for comparison. The polyimides with mDA6FPPO exhibited high $T_g$, excellent solubility, and good adhesive properties.

Phosphine oxide와 불소를 함유하는 단량체(bis(3-aminophenyl) 3,5-bis (trifluoromethyl) phenyl phosphine oxide (mDA6FPPO))를 Grignard 반응에 의하여 합성한 다음, 이를 PMDA, 6FDA, BTDA 또는 ODPA와 함께 폴리이미드 합성에 사용하였다. 폴리이미드는 폴리아믹산을 합성한 후 이를 이미드화시키는 방법을 사용하였으며, FT-IR, NMR, DSC 및 점도측정기를 이용하여 분석하였다. 또한 T-peel 시험으로 접착강도를 측정하였다. Phosphine oxide를 함유하는 bis(3-aminophenyl) phenyl phosphine oxide (mDAPPO) 및 상용의 3.3'-diamino diphenyl sulfone (mDDS)로부터 합성된 폴리이미드와 비교하였다. 본 연구에서 합성된 mDA6FPPO를 사용하여 만들어진 폴리이미드는 높은 $T_g$, 우수한 용해도 및 접착성을 보였다.
