Notes:
Two oligomeric polyaryl ether-ketone-sulfones with acetylenic end groups have been prepared. These materials which are low melting and readily soluble in organic solvents on heating undergo reactions which are presumably trimerizations of the terminal acetylenic groups to give cured polymers which do not soften until about 200°C and which are stable in circulating air at 300°C with less than 10% weight loss in 10 days.
