PHOSPHORUS-CONTAINING POLYARYLENE ETHER AND ITS PRODUCTION

Branched phosphorus-containing polyarylene ethers comprising repeating units of the structure wherein q and z are 0 or 1; and m has an average value from 1 to 10, statistically alternating with branching points units of the structures p being an integer from 1 to 4, and methods for making such ether...

Beschreibung
Zusammenfassung:	Branched phosphorus-containing polyarylene ethers comprising repeating units of the structure wherein q and z are 0 or 1; and m has an average value from 1 to 10, statistically alternating with branching points units of the structures p being an integer from 1 to 4, and methods for making such ethers by polycondensing appropriate aromatic bifunctional compounds in the presence of further condensable compounds having more than two reactive groups.
