Title:
残留モノマー含分を低下させ、かつ、吸水性架橋ポリマーフォームから形成された物品の湿潤強度を高めるための方法、及び該物品の使用
Document Type and Number:
Japanese Patent JP4284189
Kind Code:
B2
Abstract:
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.
