A number of compounds which model the ether structures found in coal were subjected to reaction in the presence of Both cyclic and non-cyclic ethers reacted provided I at least one methylene group was present adjacent to the ether oxygen atom. Complete elimination of oxygen to form water was achieved with dibenzyl and cycloaliphatic ethers but oxygen bonded directly to a phenyl or naphthyl group was converted to an unreactive phenolic hydroxyl group •

synopsisReaction rate measurements show that a Michaelis-Menten model proposed earlier is inadequate to describe the full course of the polymerization of 2,Mimethylphenol to poly(2,6-dimethyE1,4phenylene oxide). Modification of this model to include the effects of catalyst deactivation during the reaction and difference in reactivity between the monomer and other oligomers resulted in much greater accuracy. The kinetic constants in the modified model were influenced by reaction temperature, system composition, and method of catalyst component addition.
