Pentaerythrityl diphosphonate-ammonium polyphosphate combinations as flame retardants for olefin polymers |
| 摘要 |
Self-extinguishing, non-dripping polyolefin polymer compositions are prepared from a mixture of certain pentaerythrityl diphosphonates and ammonium phosphate. Dicyanopentaerythrityl diphosphonate, a new compound, is useful herein without the polyphosphate.
