Abstract
Disclosed herein is an environmentally safe, grease resistant article comprising an absorbent substrate, a cross-linking agent, and a polymer; wherein the substrate is first coated with the cross-linking agent and is then coated with the polymer.
Claims24
An environmentally safe, grease resistant article comprising:
- an absorbent substrate, and
- a uniform coating of a cross-linked polymer, the cross-linked polymer consisting of (1) about 1 to about 200 pounds of a coating polymer per ton of the substrate and (2) about 0.1 to about 400 pounds of a cross-linking agent for the polymer per ton of the substrate, and
- wherein the absorbent substrate was first treated with the cross-linking agent and then treated with the coating polymer.
