    摘要: This invention relates to crystallizing polyether polyols which can be produced firstly by the reaction of propylene oxide and polyhydroxy compounds in the presence of an alkoxy compound which contains zinc and/or aluminium atoms to form a crystallizing polyether polyol with an average molecular weight Mn from 500 to 5000, followed by the further reaction of the crystallizing polyether polyol which is thus obtained with 10 to 90% by weight, with respect to the amount of crystallizing polyol, of an epoxide in the presence of a catalyst which does not polymerize propylene oxide stereospecifically, to form a crystallizing polyether polyol with an average molecular weight Mn from 1000 to 20,000. The invention further relates to a method for the production thereof and to the use thereof for the production of polyurethane materials, particularly polyurethane foams, polyurethane elastomers and polyurethane coatings.
