Abstract

The present invention includes a composition having a co-continuous interconnecting channel morphology. These co-continuous interconnecting channels are predominately 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 and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.

Claims (11)

1. A composition comprising at least three components:

a polymer base material wherein the polymer base is a thermoplastic;

a desiccating agent;

a channeling agent, wherein the channeling agent is a material that is melted, during processing of the composition, and is a material that forms passages throughout a polymer base material, after processing of the composition; and wherein:

a) the affinity between the material that is the channeling agent and the desiccating agent is greater than between the polymer base material and the desiccating agent;

b) the desiccating agent is entrained in the polymer base material;

c) the polymer base material is a material, prior to processing of the composition, that more greatly resists diffusion of moisture than does the material that is the channeling agent;

d) the passages transmit moisture to the entrained desiccating agent in the polymer base material; and

e) the composition has at least three phases.

2. The composition of claim 1 wherein the amount of desiccating agent in the composition is between about 45% to about 60% by weight with respect to the polymer base material.

3. The composition of claim 3 wherein the amount of polymer base material in the composition is at least about 40% by weight with respect to the composition.
