【Abstract】 A novel aromatic polyester polyol was made with terephthalic acid, phthalic acid, binary alcohol, ternary alcohol and other alcohol as raw materials. The relationship between acid value, hydroxy number of the polyester polyols and the mole ratio of alcohol to acid, and the relationship between acid value and reaction time were examined, respectively. The polyester polyol was used in preparing a kind of rigid polyurethane foam plastics; the effect of the polyester polyol on the properties of the rigid polyurethane foam plastics was also diseussed.更多还原
