Polyalkenyl ether is produced by polymerizing alkenyl ether represented by the following general formula (I):CHR&#x2550;CH(OR)&#x2003;&#x2003;(I)wherein Rrepresents a hydrogen atom or a methyl group, Rrepresents a monovalent organic group, and Rcontains a silicon atom or at least one atom selected from the group consisting of elements from group 15 to group 17, in the presence of a halide of an element other than Al, or an organometallic compound of an element other than Al, and a nonionic oxygen-containing or nonionic nitrogen-containing organic compound.

Process for producing polyalkenyl ether

The present invention relates to a stimuli-responsive composition that comprises a polymer, a solvent and a substance having a predetermined function. One embodiment of the present invention is a composition comprising a block polymer, a solvent and a substance having a predetermined function. The present invention also relates to an ink composition containing the composition, an image-forming method and an image-forming apparatus using the composition, and a recording medium applying the composition. Further, the present invention relates to an ABC type block polymer compound wherein the polymer is an ABC type triblock polymer, and wherein at least one of the blocks in the triblock polymer changes in nature from solvophilic to solvophobic or from solvophobic to solvophilic in response to stimuli, and more preferably, the A component, then the B component, and finally the C component respond to the stimuli.
