<p>Provided is a vinyl ether-based star polymer which has an arm including a vinyl ether polymer and an arm including an oxystyrene polymer. Also provided is a process for producing the star polymer, which can be continuously carried out in a series of steps. Said vinyl ether-based star polymer and process for producing the same are such that the polymer includes a core and polymer-chain arm portions extending from the core, in which an arm portion including vinyl ether repeating units and an arm portion including oxystyrene repeating units are provided.</p> |
