| 摘要 |
The invention provides novel esters of glycerol, in which one of the OH groups of the glycerol is esterified with a phenolcarboxylic acid, while the two other OH groups are esterified with phosphoric or phosphorous acid, substituted by long-chain alcohols, amines, mercaptans or phenol compounds. The products are suitable as light and heat stabilizers for plastics. They are distinguished by a high resistance to hydrolysis and extraction. |
