METHOD FOR PRODUCING PARTIALLY CRYSTALLINE POLYETHER POLYOLS
摘要
The invention relates to a method for producing novel, partially crystalline polyether polyols with a functionality of >/=2 and an average molecular weight <o>M</o>n of 500 to 100,000. The mole proportion of isotactic triads determining the crystallinity is > 28 %. The novel polyether polyols are produced by polymerising alkylene oxide in the presence of a bimetallic mu -oxoalkoxide modified with hydroxyl compounds.
