摘要:
The invention relates to thermoset resins having exceptional oxidative thermal stability. The resins are prepared from thermosetting compositions containing new poly(arylacetylenes) and certain thermal stabilizers therefor. Representative stabilizers are boric acid, benzenesulfonic acid and butyl acid phosphate.
