Improved melt-processable compositions are made by graft polymerization of PEO with alkoxy silane followed. The process yields a modified resin, which, while kept relatively dry, can be fabricated into useful structures, and then, when exposed to humid air, becomes crosslinked. The result is a material that retains the versatility of thermal processability into a variety of structures along with the capability of using those structures for absorbency. This unusual combination of features is available because the crosslinked, hydrophilic network is generated after the structure is fabricated.
