1. An entrained polymer composition, comprising:

  • a polypropylene base polymer;

    a molecular sieve active agent that acts on, interacts or reacts with a selected material; and

    approximately 2% to 10% of a propylene oxide polymerisate-monobutyl ether channeling agent that is a water insoluble polymer, is immiscible with the base polymer and is adapted to transmit a selected material through the entrained polymer at a faster rate than in solely the base polymer.
