A molecule of water […] The hydrogels with dynamic boronic ester bond were prepared by simply mixing aqueous solutions of CMC–B (OH) 2 and PVA at room temperature. It was noticed the hydrogels formed almost instantly after mixing of the two solutions without any additional stimulus no matter the total concentration of 2% or 1%. Introducing a certain number of ester bonds in the backbone via radical ring opening copolymerization of acrylates with 2-methylene-1,3 dioxepane (MDO) improves its degradability and may be promising for chemical recycling. The current work examines the influence of monomer addition profiles on the copolymerization of acrylates with MDO.

In this case, “ethanoate” part comes from ethanoic acid and the “ethyl” part comes from the ethyl group on the end. Structure of Ester.
One of the partially-positive hydrogen atoms in a water molecule can be sufficiently attracted to one of the lone pairs on one of the oxygen atoms in an ester, forming a hydrogen bond. Dispersion forces and dipole-dipole attractions are also present. Forming these intermolecular attractions releases some of the energy needed to solvate the ester.
This leads to their extensive use in the fragrance and flavor industry. Ester bonds are also found in many polymers. Esterification of carboxylic acids with alcohols The reason for the solubility is that although esters can't hydrogen bond with themselves, they can hydrogen bond with water molecules.
