Abstract
An α-(unsaturated alkoxyalkyl)acrylate composition is provided which enables an α-(unsaturated alkoxyalkyl)acrylate product to be stored at a high purity for an extended period of time and can fully suppress problems such as discoloration and gelation from arising during polymerization, and a method of safely preparing α-(unsaturated alkoxyalkyl)acrylate compositions industrially, with high purity. The composition includes an α-(unsaturated alkoxyalkyl)acrylate of a specific structure and an antioxidant, the content of the antioxidant being from 0.03 to 0.5 wt % per 100 wt % of the α-(unsaturated alkoxyalkyl)acrylate.
