Substances that form channels in entrained polymers, entrained polymers containing such substances, methods for producing such entrained polymers, and products containing the same

摘要

The entrapped polymer is a base polymer, an active material that is not miscible with the base polymer, reacts with the selected material, and a water-insoluble polymer, is immiscible with the base polymer, and the selected material is faster than the base polymer alone. And a channel-forming agent that has an affinity to permeate through the contaminating polymer at a rate.
