ABSTRACT:
The present invention includes processes and resulting structures for producing a modified polymer having channels. The channels act as controlled transmission passages through the polymer. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. A channeling agent is blended then reacted into the polymer so that it is distributed within the polymer. In one embodiment, an absorbtion additive is blended into the product so that the additive is distributed within the product. The product is solidified so that the channeling agent forms passages in the product through which a desired compound is communicable to the additive 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.
