| 摘要 |
Heterocyclic-coupled linear, branched and/or crosslinked polymers of polyphenylene oxides are described which comprise poly-functional heterocyclic radicals coupled with mono- and/or polyphenoxy radicals derived from (a) polyphenylene oxides having an average hydroxyl group per molecule value greater than zero including 1.0 or less, or (b) polyphenylene oxide-quinone coupled polymers having an average hydroxyl group per molecule value greater than zero including 2.0 or less, and mixtures thereof. |
