Method for producing partially crystalline polyether polyols |
摘要 |
The present invention relates to a process for the preparation of novel, partially crystalline polyether polyols with a functionality of >=2, an average molecular weight Mn of 500 to 100,000 and a molar proportion of isotactic triads determining the crystallinity of >28%. The new polyether polyols are prepared by polymerizing alkylene oxides in the presence of a bimetallic :-oxoalkoxide modified with hydroxyl compounds.
