Synthesis and characterization of high temperature curable poly(arylene ether) structural adhesives and composite matrices
- Virginia Polytechnic Institute and State Univ., Blacksburg, VA (United States)
Crosslinked poly(arylene ether) systems are projected to display many desirable properties suitable for aerospace structural adhesive and composite matrix applications. The synthesis and characterization of a series of processable high temperature curing poly(arylene ether) oligomers incorporating terminally reactive phenylethynyl endgroups will be discussed. Characterization of the oligomers includes NMR, intrinsic viscosity, parallel plate theological behavior, TGA, and DSC. Curing of these oligomers was conducted above 380{degrees}C, providing a large processing window. Thermal stability is very good and the melt viscosity of the oligomers in the processing temperature range is exceptionally low.
