Abstract
An entrained polymer includes a base polymer, an active agent that is immiscible with the base polymer and reacts with a selected material, and a channeling agent that is a water insoluble polymer, is immiscible with the base polymer, and has an affinity to transmit a selected material through the entrained polymer at a faster rate than in solely the base polymer.
