ABSTRACT:
Acetylene-substituted aromatic ethers having very low glass transition temperatures. The compounds are useful as reactive diluents for high Tg, acetylene-terminated phenylquinoxaline oligomers. When mixed with the oligomers, the resulting compositions have a lowered Tg and the necessary flow for melt processing.
