Due to the fact that in South America old tires have been usually tied to vessels and convoys for the purpose of their lateral protection, this study was designed to address a contribution to the replacement of such material, ...

Castor oil is an environmentally friendly alternative to hydrocarbon-based feedstocks for the synthesis of polyurethanes due to its major constituent, ricinoleic acid. This work aimed to obtain and characterize castor ...

Blends made up of castor oil-based polyurethane (PU) and poly(o-methoxyaniline) (POMA) were obtained in the form of films by casting and characterized by FTIR, UV-Vis-NIR spectroscopy, and electrical conductivity measurements. ...
