PROCESS FOR PREPARATION OF A PARTICLE REINFORCED SUPER ABSORBENT POLYMER

摘要

PURPOSE: A process for preparing the titled highly water-absorbable polymer by adding an inorganic or organic filler having a melting point higher than that of a highly water-absorbable polymer to a monomer solution, polymerizing and subjecting to capture in highly water-absorbable polymer gel is provided. Whereby, the obtained polymer has excellent physical properties such as absorption power and salt absorption power as well as maintaining basic physical properties without lowering absorption power. CONSTITUTION: This titled polymer is prepared by the process consisting of: mixing 1 to 40% by weight of an inorganic or organic filler having a melting point higher than that of a highly water-absorbable polymer and a particle size of 50 to 1,000 micrometer with 0.01 to 10% by weight of a dispersing agent having an HLB value of 5 to 20 and a monomer; dispersing in a monomer solution having high fluidization; solution-polymerizing at 90 to 140deg.C for 5 to 60 min, subjecting to capture in a highly water-absorbable polymer; drying; and pulverizing.
