New polyurethanes from oxypropylated olive stone. In 25th International Symposium on Polymer Analysis and Characterization. Rolduc Abbey, The Netherlands.http://hdl.handle.net/10198/7413The purpose of this work is to explore the possibility of chemically modifying the generated polyols (oxypropylated olive stone) through reactions with isocyanates to produce polyurethanes, other than rigid polyurethane foams. This could be achieved by the chemical modification of the oxypropylation products (condensation with isocyanates) by using mono and difunctional reagents to modulate properties and/or produce useful polymer networks.engOlive stoneOxypropylationPolyurethanesBiopolyolsconference object
