Abstract

Low molecular weight fluid polyethers containing substantially unpolymerized ethylenically unsaturated groups are prepared by heating a polymerizable 1,2-epoxide containing a b ,g -ethylenically unsaturated ether group or containing a hydrocarbon group which contains an ethylenically unsaturated group directly attached to a carbon atom of the epoxide ring in the presence of an alkali metal hydroxide or an alkali metal alcoholate of an aliphatic mono- or poly-hydric alcohol and a non-polar unreactive diluent of boiling point within the range 70-160 DEG C. Suitable epoxides include alkyl glycidyl ether and alkyl analogues thereof and butadiene monoxide. Copolymers may be obtained with 1,2-epoxides not containing ethylenically unsaturated groups (e.g. "styrene" oxide in Example 11). Linear polyethers are obtained with hydroxide catalysts or those derived from mono- or di-hydric alcohols unless some diepoxide is present and branched polyethers with tri- or higher hydric alcoholates. Suitable diluents include aliphatic and aromatic hydrocarbons. An excess of the alcohol corresponding to the catalyst may be present. Catalyst residues may be removed by neutralizing with a cation exchange resin or an inorganic or organic acid or anhydride and filtering off the insoluble salt formed.ALSO:Low molecular weight fluid polyethers containing substantially unpolymerized ethylenically unsaturated groups are prepared by heating a polymerizable 1,2-epoxide containing a b ,g -ethylenically unsaturated ether group or containing a hydrocarbon group which contains an ethylenically unsaturated group directly attached to a carbon atom of the epoxide ring in the presence of an alkali metal hydroxide or an alkali metal alcoholate of an aliphatic monoor poly-hydric alcohol and a non-polar unreactive diluent of boiling point within the range 70 DEG C.-160 DEG C.
