摘要：<p>The invention relates to a process for producing a water-absorbing material by coating water-absorbing polymer particles with a film-forming polyurethane and pyrogenic silica and heat treating the coated particles. The invention further relates to the water- absorbing material obtainable according to the process of the invention. The water- absorbing material has improved wicking ability (FHA) and fixed swell rate (FSR).</p>
