摘　　要：用对苯二甲酸、苯酐、二元醇、三元醇等多元醇为原料制备新型芳香族聚酯多元醇,考察了聚酯多元醇酸值、羟值与其醇酸摩尔比的关系,以及酸值与反应时间的关系,并将其用于制备硬质聚氨酯泡沫塑料,讨论了新型聚酯多元醇对硬质聚氨酯泡沫塑料的性能影响。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.
