titleOfInvention |
Polycarbonate compositions comprising hindered amine light stabilizers |
abstract |
The instant invention relates to weatherable polycarbonate compositionsn(formulations or blends) comprising piperazinone or piperazine dione basednHALS. These piperazinone or piperazine dione based HALS impartnphotostability to the polycarbonate formulations, thereby reducing yellowing ornother forms of light induced degradation. |
