Method for disintegrating hydrate polymer and method for production of water-absorbent resin |
摘要 |
A method for disintegrating a hydrate polymer characterized by disintegrating a hydrate polymer having a solid content in the range of 50-70 wt. % with a screw extruder while supplying 0.1-30 parts by weight of water per 100 parts by weight of the polymer to the extruder. Since the product of disintegration is prevented from inducing mutual adhesion, it does not form masses of conglomeration when it is dried.
