| 摘要 |
Polyester compositions containing organophosphorus derivatives as stabilizers are disclosed. Methods of stabilizing polyesters are also provided by incorporating the organophosphorus derivatives during processing to prevent thermal and catalytic decomposition, and with improvements in resin color, molecular weight retention and mechanical properties. This invention also affords an efficient method of inhibiting the decomposition activity of the first stage catalyst in the production of high polymeric condensation polyester resins. |
