Abstract:
1. A process for producing a polyalkenyl ether by polymerizing an alkenyl ether represented by general formula (II): where R the process comprising the steps of: mixing the cation source and the first Lewis acid to generate initiator cations; and subsequently adding the alkenyl ether represented by the general formula (II) and the second Lewis acid for initiating a high-speed polymerization reaction, wherein the first Lewis acid is a halide or an organometallic compound of an element selected from the group consisting of Mg, B, Al, Si, and P, the second Lewis acid is a halide or an organometallic compound of an element of the fourth period or higher in the periodic table, and the cation source is a proton acid, water, an alcohol, a halide, a hydrogen halide, or an adduct of a carboxylic acid and a vinyl ether, wherein the alkenyl ether represented by the general formula (II) and the first Lewis acid are used at a molar ratio in a range of 10 to 1000, and wherein the alkenyl ether represented by the general formula (II) and the second Lewis acid are used at a molar ratio in a range of 10 to 1000.
