| titleOfInvention | Method for the preparation of a particulate reversibly crosslinked polymeric material |
| abstract | The present invention relates to method for the preparation of a particulate reversibly-crosslinked polymeric material comprising: treating a particulate water-soluble hydroxyl-functional polymer in a liquid phase comprising a solvent mixture in that the hydroxyl-functional polymer is insoluble containing an organic solvent and water; a tetracarboxylic acid dianhydride represented by formula (I), 10 (I) wherein: U and V are independently selected from CH, N and P; 15 X is selected from a single bond, a saturated divalent (C 1 -C 10 ) hydrocarbon group, O, S, NR, and PR, wherein R is selected from hydrogen and (C 1 -C 4 ) alkyl; n and m are independently selected from 0 and 1; w is 1 or 2 with the proviso that; 20 if w is 1 then Y is X and if w is 2 then Y is selected from H and (C 1 -C 4 ) alkyl, whereby there is no bond between both Y; and optionally a catalyst; to form a particulate reversibly-crosslinked polymeric material and 25 to a particulate reversibly-crosslinked polymeric material obtainable thereby. |
