When temperature rise over to a Reactive Temperature ( Tr ), water will be released. When temperature decline to the threshold temperature, the polymer will absorb water again. When the NIPAAm polymer were mixed to soil, the compound will absorb rainwater and irrigation. When soil temperature rise, the NIPAAm polymer will set free the store water to soil. For this reason, the NIPAAm polymer is the most effective water retaining materials. Because the NIPAAm polymer provide water to soil, but not store water in polymer only. The NIPAAm polymer is different from others water absorptive polymer that unique we had known.
