Abstract

Polyurethanes based on biopitch and PEG of distinct molecular masses (M w 1500, 4000 and 6000) were synthesized using polymeric MDI. Different materials were obtained through syntheses using various biopitch content and NCO/OH ratio. Thermogravimetric analysis (TG) and differential scanning calorimetry (DSC) were used to determine their thermal properties. Variations of thermal stability were observed with amorphous and semicrystalline structures depending on the biopitch content and the NCO/OH ratio.
