| abstract |
The present invention relates to a hindered amine compound having at least two nitrogen atoms having different basicities. One is substituted on the N atom by an alkoxy moiety and the other is substituted on the N atom by a hydroxy-alkyl moiety. These materials are particularly effective in stabilizing polymers, especially thermoplastic polyolefins, against the adverse effects of oxidative radiation, thermal radiation and actinic radiation. The compounds are also particularly effective in stabilizing acid catalyst coating systems and room temperature curing coating systems. |
