Foamed polymeric materials |
摘要 |
Foamed water-swellable polymeric water absorbent materials are prepared by contacting a polymer capable of having a water-swellable character and containing acid moieties in acid form with a blowing agent such as sodium bicarbonate, which blowing agent is capable of neutralizing the acid moieties of the polymer. The foamed polymers are useful in a wide variety of water absorbent applications.
