Abstract
This invention relates to a method for the purification of glycidyl acrylate or glycidyl methacrylate. Specifically, the invention effects the purification by using a residual catalyst-inactivating additive and consequently produces highly purified glycidyl acrylate or glycidyl methacrylate containing substantially no epichlorohydrin and having a low chlorine content.
