Patent Abstracts

Foams are well known and very useful.  Multifunctional foams are always of interest and expand applications.

Wibaux and Paesen of Avery Dennison develop an odor absorbing foam based on cyclodextrin coupled to  polyurethane foam.  This foam is produced by mixing cyclodextrin, polyurethane prepolymer and reacting the mixture with water.  (Wibaux and Paese, US Patent 8,741,977, 6/3/2014)
