摘　　要：使用自制的稳定分散剂(SDA)替代现有大分子单体分散剂D合成目标固体质量分数为45%的聚合物多元醇(POP)产品。考察了SDA含量对POP性能的影响,并将其与分散剂D合成POP产品进行对比。结果表明,使用自制稳定分散剂SDA合成固体质量分数45%的POP时,可使POP粘度较原来降低约2300 mPa·s(25℃),并且由SDA合成POP所发的泡沫力学性能与大分子单体分散剂D合成的泡沫力学性能相当。Polymer polyol （ POP） with solid content of 45% was compounded by stable dispersant（ SDA） repla-cing dispersing agent D. Influence of stable dispersant mass fraction on POP properties was investigated. The prod-uct was compared with compound by dispersing agent D. The results showed that the POP viscosity was decreased about 2300 mPa·s（25 ℃） when the product with solid content of 45% was compounded by SDA. The foam me-chanical properties from POP by SDA were similar with the POP by dispersing agent D.
