(57) [Summary]nThe present invention includes a process and a resulting structure for producing a modified polymer having interconnecting channels. The interconnect channel acts as a controlled passageway through the polymer. The hydrophilic agent is blended with the polymer such that it is distributed within the polymer. In one embodiment, the absorbent and release material is blended with the polymer such that the absorbent and release material is distributed within the product. The product solidifies and the hydrophilic agent forms a passageway in the product through which it can communicate with the absorbing and releasing material entrained in the product. The solidified product can be used to form the desired molded article, such as plug-type inserts and liners for closed containers, or it can be formed into films, sheets, beads or pellets. |
