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.
Claims11
An entrained polymer composition, comprising:
- a base polymer;
- a desiccant that is immiscible with the base polymer and acts on, interacts or reacts with moisture;
- a channeling agent selected from the group consisting of a propylene oxide polymerisate and a propylene oxide polymerisate-monobutyl ether;
- a plurality of channels throughout the entrained polymer, formed by the channeling agent, wherein at least some of the desiccant is located within the plurality of channels, and the plurality of channels transmit the moisture between the desiccant located within the plurality of channels and the exterior of the entrained polymer;
- wherein the entrained polymer composition forms a monolithic composition.
