Resumen:
Pressure-sensitive adhesives (PSA) are tacky, viscoelastic materials that can adhere instantly to a variety of substrates under light pressure at room temperature without chemical changes. Applications of PSA are diverse, ranging from tapes to packaging [1-3]. Since commercial PSAs are mainly based on petrochemical-derived polymers, the development of such kind of adhesives from biogenic resources is one of the research challenges of the present time. Efforts in producing PSAs from fatty acids and esters derived from plant oils are reported in the latest literature , mainly because fatty acid and derivatives are among the most attractive starting materials due to their renewable nature, universal availability, biodegradability and low cost . In this work, we a studied the potential of epoxidized soybean oil and two different di-carboxylic acids , a commercial sebacic acid and a home-made di-carboxylic fatty acid from undecenoic acid through thiol-ene click reaction , as alternative sources to produce PSAs with tailored properties.
