What is the effect of the concentration of hydroxyethyl acrylate on the self polymerization reaction?

The concentration of hydroxyethyl acrylate HEA is also a very critical factor. If the concentration is too low, the self-polymerization reaction may be difficult to occur because the chance of molecular collisions decreases. If the concentration is too high, the reaction may become too violent, easily producing by-products. Therefore, controlling the concentration is very important. Generally speaking, in self-polymerization experiments, the concentration of hydroxyethyl acrylate hea is usually controlled between 5% and 50%. Within this range, the reaction can proceed smoothly and the quality of the polymer product can be ensured.

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.
