Cork suberin as a new source of chemicals: 2. crystallinity, thermal and rheological properties.

A sub stantial proportion of these oligomers possessed a microcrystalline character with a melting range between 0 and 50°C. The amorphous part was liquid at room temperature and did not display a detectable glass transition upon cooling because of its wide molecular weight distribution. The viscous behaviour of suberin at room temperature was both plastic and thixotropic because of the structuring role of the microcrystals.engCork of Quercus suber L.Alkaline methanolysisSuberinThermal characterizationRheological propertiesCrystallinityDensity.Faculdade de Ciências Exatas e da Engenhariajournal article10.1016/S0960-8524(97)00073-4
