Hydrolytic and melt degradation stabilized polyester |
| abstract |
WHERE N > OR = 3. The polyester is thereby stabilized without either substantial poisoning of the catalyst, degradation of the polymer or loss of substantial amounts of phosphorus-containing compound. Low carboxyl end group polyesters are stabilized against melt degradation and strength loss by the addition to the polyester, after the polycondensation stage, of stabilizing amounts of polyphosphoric acid having the structure |
