A PROCESS FOR THE REDUCTION OF THE RESIDUAL MONOMER CONTENT AND ENHANCEMENT OF THE WET STRENGTH OF ARTICLES FORMED FROM WATER ABSORBENT CROSSLINKED POLYMER FOAMS AND USE THEREOF |
摘要 |
<p>A process for the reduction of the residual monomer content and enhancement of the wet strength of articles formed from water absorbent crosslinked polymer foams containing units derived from monoethylenically unsaturated acids, which comprises treating the formed articles with at least 0.5% by weight of a polymer containing primary and/or secondary amino groups and having a molar mass of at least 300, the formed foam articles thus obtainable and use of the wet strength enhanced formed foam articles in hygiene articles.</p> |
