The present invention relates to a process for direct production of mixtures of short-chain high-functionality polyoxyalkylene polyols and long-chain low-functionality polyoxyalkylene polyols. The short-chain high-functionality polyoxyalkylene polyol component is obtained by alkylene oxide addition onto high-functionality H-functional starter compounds while the long-chain low-functionality polyoxyalkylene polyol component is correspondingly obtained by alkylene oxide addition onto low-functionality H-functional starter compounds. The invention further relates to the resulting polyoxyalkylene polyols and to the reaction thereof to produce polyurethanes. 本发明涉及直接制备短链高官能聚氧化烯多元醇和长链低官能聚氧化烯多元醇的混合物的方法。该短链高官能聚氧化烯多元醇组分通过使环氧烷加成到高官能H官能起始剂化合物上获得，而相应地，该长链低官能聚氧化烯多元醇组分通过使环氧烷加成到低官能H官能起始剂化合物上获得。本发明的另一主题是由此产生的聚氧化烯多元醇及其用于制备聚氨酯的反应。
