Thermal Reaction Properties of Perfluorinated Poly(arylene ether) with Acetylenic End Groups |
| 초록 |
Fluorinated ether oligomer with a crosslinkable ethynyl group at the chain end (FPAE-EP) was synthesized by the reaction of 4,4'-(hexafluoroisopropylidene)diphenol with an excess decafluorobiphenyl, followed by reaction with m-ethynylphenol. The molecular weight (Mn) and polydispersity (Mw/Mn) of FPAE-EP were 7,800 and 1.79, respectively. The studies on the curing behaviors of FPAE-EP were performed by such instrumental methods as dielectrometry, differential scanning calorimetry, and FT-IR spectroscopies. The FPAE-EP showed the lowest ionic viscosity around 202 ℃, and then the ionic viscosity was gradually increased up to 271 ℃. This means that the crosslinking reaction of FPAE-EP start at 202 ℃ and the molecular weight is increased by the accelerated thermal crosslinking reaction of the terminal acetylene functions. The loss factor behaviors of FPAE-EP, which is related to the fluidity of matrix, were found to be similar with that of ionic viscosity. |
