What is the special structure of hydroxyethyl acrylate molecules?

The molecule of Hydroxyethyl Acrylate has a special structure, namely its double bond. This double bond is very important and is the key to the self-polymerization reaction of hydroxyethyl acrylate. Simply put, when this substance is exposed to a suitable environment under appropriate conditions, it will react with itself to form a polymer. Sounds amazing, doesn’t it?

The structure of hydroxyethyl acrylate HEA determines that it has a certain polarity. Due to the difference in electronegativity of different atoms in the molecule, the charge distribution is uneven. This polarity allows it to be well miscible with some polar solvents, such as ethanol and water.
