HIGHLY ABSORBENT SUBSTRATE ARTICLE

摘要

A reusable highly absorbent article, for example a cloth or towel for mopping up household spillages, comprises a substrate carrying a pressure-sensitive polymeric material capable of absorbing, retaining, releasing and reabsorbing large volumes of of water or electrolyte. The polymer is preferably the sulphonation product of a high-void-volume styrene polymer prepared by polymerisation of a high-internal-phase emulsion.
