| titleOfInvention | Process for producing improved absorbent polymer by low temperature grinding |
| abstract | The present invention relates to a method for producing a water-absorbing polymer, the method comprising the following steps: (I) Mixed (α1) 0.1 to 99.99% by weight, preferably 20 to 99.99% by weight, more preferably 30 to 98.95% by weight, containing polymerized acid groups or salts thereof An ethylenically unsaturated monomer, or a polymerized ethylenically unsaturated monomer containing protonated nitrogen or quaternary nitrogen, or a mixture thereof, particularly preferably at least an acid group, preferably acrylic acid. A mixture comprising an ethylenically unsaturated monomer containing in a neutralized part, (α2) 0-70% by weight, preferably 1-60% by weight, more preferably 1-40% by weight, one or more ethylenically unsaturated monomers copolymerizable with α1), (α3) 0.001 to 10% by weight, preferably 0.01 to 7% by weight, more preferably 0.05 to 5% by weight. (Α4) 0-30 wt%, preferably 1-20 wt%, more preferably 5-10 wt% water-soluble polymer, and (α5) 0-20 wt%, preferably 0.01- One or more supplements of 7% by weight, more preferably 0.05-5% by weight, the sum of the weights of (α1) to (α5) being 100% by weight; (ii) water-insoluble (Iii) Coarse grinding of the raw hydrogel polymer to give fragments having a diameter in the range of 0.1 mm to 5.0 cm; (iv) ) Cooling of the pre-ground raw hydrogel polymer and grinding of the cooled raw hydrogel polymer; (v) Drying of the ground raw hydrogel polymer after grinding at a temperature in the range of 85 ° C. to 260 ° C. And sieving to pieces dried ranging 150μm~850μm; (vi) after the hydrogel polymer crosslinking, and, (vii) Drying and finishing of the water-absorbing polymer. [Selection figure] None |
