| titleOfInvention | Process for preparing swellable, aging resistant starch maleates: biodegradable starch maleates and their use |
| abstract | Production of swellable starch maleate (I) that is resistant to ageing comprises reacting a swellable starch maleate (II) with mono- and/or poly-functional nucleophilic reagent(s) (III) by Michael addition. Also claimed is biodegradable (I) obtained in this way. (III) is a mercapto compound, especially mercaptoethanol (IIIA), 1,2-bis-(2-mercaptoethoxy)-ethane (IIIB) or a mixture of (IIIA) and (IIIB), especially 0.001-0.5 equivalents (equiv.) (IIIB) and 0.5-0.999 equiv. (IIIA) per equiv. maleic anhydride in (II); sodium bisulphite (NaHSO3); pentaerythrityl tetrakis-(2-mercapto-acetate) (IIIC); or a mixture of NaHSO3 and (IIIC), especially 0.001-0.5 equiv. (IIIC) and 0.25-0.999 equiv. NaHSO3 per equiv. maleic anhydride in (II). |
