Abstract

Alkylene oxides are polymerized under anhydrous conditions in the presence of (a) a catalyst comprising an alkoxide or aryloxide of a coordinating di-, tri- or tetra-valent metal having an ionic radius of 0,2 to 0,98 , an atomic radius of less than 1,6 , an atomic weight of less than 66, and being selected from chromium and Group 2, 3, 4 and 8 of the Periodic Table, in which only alkoxide or aryloxide groups are attached to the metal, and (b) a co-catalyst which is an oxide, chloride or bromide of a mono- or di-valent metal having the same atomic characteristics as above and being in Group 1, 2 or 8 of the Periodic Table. The alkylene oxides are those having a ring of 2 carbon and 1 oxygen atom, and mixtures may be used. Specified catalysts of class (a) are the alkoxides of aluminium, chromium, iron, magnesium, titanium, cobalt and nickel, particularly the methoxide, ethoxide, isopropoxide and butoxide of aluminium and their halo-substituted derivatives. The co-catalysts are preferably chlorides, e.g. of p zinc, beryllium, lithium and cobalt. In addition, an auxiliary catalyst may be added, consisting of an alkyl alkoxide of aluminium or zinc. Examples of alkylene oxides are ethylene, propylene, butylene, pentylene, hexylene and duodecylene oxides and butadiene monoxide. They may be substituted by groups which do not react with alkaline materials. Proportions of each catalyst component and of catalyst mixture may vary over wide ranges, as may the temperature and pressure. Solvents such as hydrocarbons, chlorinated hydrocarbons and ether may be present. The catalyst may be removed from the polymer by recrystallizing the polymer from solution by lowering the temperature. Hydroxy- or amine-substituted polymers may be cured with isocyanates or dicarboxylic acids. Examples are given, specifying intrinsic viscosities (of the order of 2 to 4) and, in Example 1, a molecular weight of 220,000. Specifications 765,054, 859,257 and 893,275 are referred to. Reference has been directed by the Comptroller to Specifications 785,053, 785,229 and 793,065.
