Mirta Aranguren, professor of chemical engineering in the polymer division at University Mar del Plata, will present "Bio-based Composites: Vegetable Oils and Cellulosic Reinforcements" on Tuesday, March 17, at 2 p.m. in 104 Textile Building. Her seminar is hosted by Auburn University's Department of Polymer and Fiber Engineering.

As environmental considerations become more prevalent around the world, there is an increasing demand for renewable resources used in the production of eco-friendly materials. Vegetable oils, formed by triglyceride molecules, are abundant, widely available and relatively low-cost.

These molecules offer the possibility of many different modifications that can be used in the preparation of monomers, resins and polymers. Two examples are the use of linseed oil to obtain an unsaturated polyester resin and the preparation of polyurethanes from tung oil and castor oil.
