Monolithic polymer composition having a releasing material

摘要: The present invention includes processes and resulting structures for producing a modified polymer (25) having interconnecting channels (45). (45) act as controlled transmission passages through the polymer. A hydrophilic agent (35) is blended into so that it distributed within In one embodiment, an absorbing material (30) product. product solidified forms in which desired composition communicable to entrained may be used form shaped article such plug type inserts (55) liners (70) closed containers, or formed film, sheet (75), bead, pellet.
