Abstract
Fluorocarbon ether bibenzoxazole oligomers having reactive terminal acetylenic groups which make it possible to thermally cure the oligomers without the evolution of volatiles to rubbery vulcanizates exhibiting high thermooxidative stability and low temperature flexibility, properties that render the materials suitable for various aerospace applications such as for seals and sealants.
