Thermally stable carbonate polymer |
| abstract |
ABSTRACT OF THE DISCLOSURE This invention is directed to a carbonate polymer having improved thermal stability wherein the polymer has copolymerized therewith an effective amount of an oligomer having the formula H - [O-R-O-P (ORl)]n - O-R-OH wherein R is the divalent residue of a dihydxic mononuclear phenol or a dihydric polynuclear phenol, R1 is an alkyl, aralkyl or alkaryl group having from 1 to 25 carbons, and n is a number having an average value from 1 to 200. |
