| titleOfInvention | Method of producing additionally cross-linked water-absorbing polymer particles with high absorption by polymerising droplets of solution |
| abstract | FIELD: chemistry.SUBSTANCE: described are water-absorbing polymer particles with centrifugal retention capacity (CRC) of at least 20 g/g and absorptionm under a load of 4.83 kPa (AUL0.7psi), which satisfy the condition AUL0.7psi?-0.017CRC+1.5CRC-6. The polymer particles have average sphericity of at least 0.84 and hydrophobic solvent content of less than 0.005 wt %. Also described are water-absorbing polymer particles with average sphericity of at least 0.84, hydrophobic solvent content of less than 0.005 wt %, and CRC of at least 20 g/g and free swell rate (FSR) which satisfies the condition FSR? -0.00082 CRC+0.07CRC-0.95. Described is a method of obtaining said particles by polymerising droplets of a monomer solution which contains a) at least one at least one ethylenically unsaturated monomer having at least one acid group, b) at least one cross-linking agent, c) at least one initiator, d) water in the gas phase surrounding the droplets, the obtained polymer particles being additionally cross-linked, wherein content of solid substance of the monomer solution is at least 35 wt %, and the monomer solution is added in droplets to the gas phase to form a monodispersion droplet chain, and wherein the polymer particles have mean diameter of at least 150 mcm, wherein the process is carried out, if necessary, in the presence of a hydrophobic solvent. Use of said polymer particles to obtain sanitary and hygiene products is also described.EFFECT: obtaining water-absorbing polymer particles with an improved profile of characteristics, high permeability, high centrifugal retention capacity, high absorption under load and high free swell rate.27 cl, 1 dwg, 3 tbl, 9 ex |
