Pressure-Sensitive Adhesives Based on Epoxidized Soybean Oil and Dicarboxylic Acids
Summary
This learning object examines the development of environmentally friendly pressure-sensitive adhesives (PSAs) synthesized from epoxidized soybean oil (ESO) and bio-based dicarboxylic acids via an epoxide–acid reaction. The study investigates the influence of crosslinking density, monomer ratios, and curing conditions on adhesive performance, including tack, peel strength, and shear resistance. The resulting PSAs demonstrate competitive adhesive properties compared to petrochemical-based counterparts while utilizing renewable resources. Through systematic variation of composition and processing, the research illustrates how bio-based polymers can be tailored for targeted applications in adhesives, reducing environmental impact without sacrificing functionality.
This work embodies the principles of green chemistry by replacing petroleum-derived PSA components with renewable, plant-based feedstocks, specifically soybean oil and dicarboxylic acids. It demonstrates:
1. Use of renewable feedstocks by employing ESO and bio-based acids.
2. Designing safer chemicals by reducing the use of volatile organic compounds common in PSA formulations.
3. Energy efficiency via mild reaction conditions and solvent-free synthesis.
4. Design for degradation by using biodegradable monomers that support end-of-life environmental compatibility.
Students can learn how chemical structure influences material properties, how renewable feedstocks can meet industrial performance standards, and how to integrate sustainability principles into polymer and adhesive design.
