PPQ's Containing Pendent Ethynyl and Phenylethynyl Groups
Abstract
Polyphenylquinoxalines (PPQ's) containing cross-linking groups have higher use temperature and solvent resistance. As polymers are exposed to elevated temperatures, thermally induced reaction of pendent groups occurs to provide cross-linking, which raises use temperature of polymer and improves solvent resistance.
