Abstract:

In accordance with the method of manufacture described herein, it has been found that by applying a polymerization catalyst or polymerization initiator directly to a liquid-absorbent or liquid adsorbent (hereinafter collectively referred to as “liquid-sorbent”) substrate, preferably a porous geotextile in sheet material form, to form a polymerization-initiating substrate or sheet material, a monomer that is subsequently embedded in the liquid-sorbent substrate will be completely contacted by the polymerization catalyst or polymerization initiator for complete polymerization of the embedded monomer to form embedded polymer solids, without the monomer partially polymerizing before contacting the substrate. It has been found that complete polymerization of the monomer while in contact with the substrate achieves best results in retention of embedded and interlocked polymer solids. Preferably only the polymerization catalyst or polymerization initiator, and optionally a cross-linker for the monomer, is applied to the porous substrate prior to embedding the monomer into the substrate.
