Abstract
⺠Polyurethane foams could not be directly prepared from heavy oil for its low hydroxyl number. ⺠After modification, heavy oil increased its hydroxyl number to 564.5 mg KOH/g. ⺠Furthermore, the secondary alcohol hydroxyl was the main product. ⺠The compressive strength of foams increased 32% by adding 10% activated heavy oil. ⺠However, adding 100% activated heavy oil would weaken the properties of PU foams.
