| 摘要 |
The invention relates to mixed esters of phosphorous or phosphoric acid having on the one hand open chain polyalcohols and on the other hand long chain alkyl compounds with activated hydrogen, for example, alcohols, mercaptans and amines. The compounds are suitable as light and heat stabilizers for polyolefins and for chlorine-containing thermoplastic compositions and are furthermore distinguished by a high resistance to hydrolysis. |
