    摘要: A process for producing a polycyanoaryl ether powder which comprises reacting a dihalogenobenzonitrile, a dihydric phenol and an alkali metal salt in the presence of a polymerization solvent, and distilling the solvent, while pulverizing the reaction mixture under agitation. The process produces a polycyanoaryl ether powder having excellent physical properties and is useful as a material for electronic appliances, electric appliances and parts of machines.

    摘要: A process for producing an ether compound represented by the general formula (II) or (III): ##STR1## wherein R.sup.1 and R.sup.2 represent each an alkyl group or a cycloalkyl group and n represents an integer of 1 to 50, which comprises bringing an acetal compound represented by the general formula (I): ##STR2## into reaction with hydrogen in the presence of a solid catalyst comprising (A) nickel in an amount corresponding to 10 to 70% by weight of metallic nickel, and (B) at least one compound selected from the group consisting of oxides of silicon, aluminum, magnesium, titanium, and zirconium; and synthetic or natural inorganic oxides containing one or more of these oxides as the constituents thereof. A vinyl ether polymer having a terminal ether group can be obtained with a good yield without causing corrosion of the apparatus used for the reaction.
