Pressure sensitive adhesive (PSA) products have become ubiquitous in our homes and offices through address labels, stamps, sticky notes, and tapes. The majority of these PSAs are based on petroleum-derived acrylates. In 2006, more than 300 million dry pounds of acrylic adhesive was sold in the United States. Incorporation of biomass-derived resources as a substitute for acrylates will make a significant contribution in the development of sustainable products.
We developed PSAs with high biomass-content using biomass-based macromonomers, which can copolymerize with standard adhesive acrylates and replace 40-60% of petroleum-based raw materials. The work described here is an example of a novel, yet pragmatic approach to develop sustainable PSA formulations by simple modifications of successful commercial products, while maintaining performance.
