Abstract: IN A PROCESS FOR PREPARING WATER-ABSORBENT RESING BASED ON ACRYLIC ACID, CRUDE ACRYLIC ACID IS FIRSTLY ISOLATED FROM THE REACTION GASES FROM THE CATALYTIC GAS-PHASE OXIDATION OF PROPANE, PROPYLENE AND/OR ACROLEIN. THIS IS TREATED WITH AN ALDEHYDE SCAVENGER AND PURE ACRYLIC ACID IS SEPARATES BY DISTILLATION FROM THE TREATED CRUDE ACRYLIC ACID, AND THIS PURE ACRYLIC ACID CAN BE SUBJECTED DIRECTLY TO A FREE-RADICAL POLYMERIZATION.(FIG 1)
