VERFAHREN ZUM BINDEN VON TEILCHENFORMIGEN, WASSERABSORBIERENDEN, SAUREGRUPPEN ENTHALTENDEN POLYMEREN AN EIN TRAGERMATERIAL |
摘要 |
<p>A process for binding particulate water-absorbing acid-functional polymers to a carrier material by means of compounds comprising amino groups, which comprises contacting the carrier material with particulate water-absorbing acid-functional polymers whose acid groups have been 0 to not more than 55 mol % neutralized with alkali metal and/or ammonium bases and then raising the degree of neutralization of these polymers to not less than 60 mol % by treatment with amino-containing compounds. The use of compounds comprising amino groups and selected from the group of the compounds consisting of the alkanolamines and compounds which contain ethyleneimine and/or vinylamine units to neutralize and bind particulate water-absorbing acid-functional polymers neutralized 0 to not more than 55 mol % with alkali metal and/or ammonium bases to a carrier material.</p> |
