Used primarily as a monomer in the synthesis of high-performance polymers, especially in the production of water-dispersible or water-soluble polyesters and polyamides. Its hydrophilic ethoxy group enhances solubility and processability, making it valuable in coatings, adhesives, and textile applications where controlled solubility and environmental resistance are required. Also employed in the formulation of crosslinking agents and as a building block for specialty polymers used in inkjet printing, electronic materials, and biocompatible films. Its ability to introduce both rigidity and polarity into polymer chains allows for fine-tuning of thermal and mechanical properties.
