| abstract |
The present invention includes a composition (25) having a co-continuous interconnecting channel morphology (45). These co-continuous interconnecting channels are predominantly occupied with a polymer and particles that control the percolation through the composition. The particles are composed of a material such as an absorbing agent, releasing agent and/or activation agent. The polymer composition may be used to form a desired shaped article such as plug type inserts (55) and liners (70) for closed containers (60), or it may be formed into a film, sheet (75), bead or pellet. |
