ABSTRACT:
A polymeric composition comprising a poly-2-oxazoline reacted by transamidation with a carboxylic acid, anhydride, salts of a carboxylic acid or combination thereof which can be blended with another polymeric composition to form a water wettable blend. In another aspect, the poly-2-oxazoline is crosslinked with a polybasic carboxylic acid by transamidation. The crosslinked polymeric composition is useful as an absorbent for polar materials.
