  PROBLEMS: To easily and efficiently obtain a high quality (meth) acrylate-based polymer containing small residual amount of metal components (an aluminum component, an alkali metal component and other metal components) and having high purity and excellent properties such as heat resistance, transparency and others. MEANS FOR SOLVING THE PROBLEMS: The present invention provides a method of obtaining a (meth)acrylate-based polymer by adding an acid to a reaction solution containing the (meth) acrylate-based polymer obtained by polymerizing a (meth) acrylate-based monomer in a water-insoluble organic solvent in the presence of a metal compound such as a metal-containing polymerization initiator, an organoaluminum compound and the like, washing the reaction solution to which the acid has been added by admixing water at 90°C or more, separating the mixed solution of the reaction solution and water generated by washing into an organic solvent solution layer and an aqueous solution layer, isolating the organic solvent solution separated into a layer, and obtaining the (meth)acrylate-based polymer out of the solution. Also provided is a high-purity (meth)acrylate-based polymer having excellent transparency obtained by the method.
