摘要
介绍了聚酯聚合物多元醇以及大分子分散剂端羟基预聚体、巯基改性聚酯多元醇和顺丁烯二酸酐(MA)改性聚酯多元醇的制备方法,对合成聚酯聚合物多元醇所需的原料提出了具体要求。聚酯聚合物多元醇用于制备聚氨酯软质泡沫具有一定的价格优势。
The process and preparation methods of polyester polymer polyols, macromolcular dispersant of OH-terminated prepolymer, sulfhydryl group modified polyester polyols, maleic anhydride modified polyester polyols were introduced. A demand for materials of producing polyester polymer polyol was refered. The polyester polymer polyols for production of flexible PU foams had the advantages in the price.
