PROCESS FOR THE PREPARATION OF HEAT-STABLE OLEFIN POLYMERS |
| 摘要 |
The addition of hindered amines in combination with a phosphorus-III-ester to the polymerisation of olefins on spherical Ziegler-Natta catalysts effects a thermo-oxidative stabilisation of the prepared polymers. Phenolic antioxidants may be used additionally.
