Cork was chemically modified with the purpose of reaching a better understanding of its reactivity in heterogenous systems, and obtaining novel products with potential applications in the realm of polymeric materials. Several cork particles were oxypropylated under pressure at a relatively high temperature and yielded a mixture of liquid polyols composed of propylene oxide homopolymer (PPO) and cork macromolecules bearing oligo(propylene oxide) grafts. The solid residue was characterized by Fourier transform infrared (FTIR) spectroscopy only, whereas the two viscous polyols were submitted to FTIR, H- and C- NMR spectroscopy, differential scanning calorimetry, gel permeation chromatography, vapor pressure osmometry, bulk viscometry and OH number.
