MONOLITHIC POLYMER COMPOSITION HAVING AN ACTIVATION MATERIAL

摘要

The present invention includes processes and resulting structures for producing a modified polymer having interconnecting channels. The interconnecting channels act as controlled transmission passages through the polymer. A hydrophilic agent is blended into the polymer so that it is distributed within the polymer. In one embodiment, an absorbing and releasin g material is blended into the polymer so that the absorbing and releasing material is distributed within the product. The product is solidified so tha t the hydrophilic agent forms passages in the product through which a desired composition is communicable to the absorbing and releasing material that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.
