| 摘要 |
Polymers (P) based on (co)poly-.alpha.-hydroxyacrylic acid, optionally in a lactonised or salt form, optionally as Mg complexes, are characterised by containing carbohydrate units and 2-hydroxy-2-carboxyethylene-1,2 monomer units and are useful as biodegradable, alkali-resistant stabilisers for peroxide bleaching agents. |
