Abstract

Waxy to solid halgenated poly alkylene oxides having a 5% aqueous solution viscosity of 10 to 500,000 cps. are prepared by reacting a high molecular weight solid poly alkylene oxide containing certain catalyst residues with a halogenating agent, the product having an average molecular weight lower than that of the starting polymer. The catalyst residues are those of amides of calcium, strontium, barium, zinc and cadmium, hexammoniates of calcium, strontium and barium, or decomposition products of these hexammoniates which contain only the metal, nitrogen and hydrogen. Suitable polymers are polyethylene oxide, poly propylene oxide and copolymers of ethylene oxide with other alkylene oxides. The halogenating agent may be any halogen or an alkali metal or alkaline earth metal hypochlorite. The resin may be treated as an aqueous slurry or as a supsension in an organic liquid such as heptane, carbon tetrachloride or chloroform, or as a finely divided powder. Halogenating gases may be diluted with inert gases. Residual halogen may be neutralised after the reaction with ammonia or an amine. Examples are given.
