Used as a versatile polymeric surfactant and coupling agent in drug delivery systems, enhancing solubility and bioavailability of poorly water-soluble drugs. Its amphiphilic block structure enables self-assembly into micelles, making it ideal for nanocarrier formulations in targeted cancer therapy. Also employed in tissue engineering as a scaffold modifier due to its biocompatibility and ability to promote cell adhesion. Commonly used in coatings and adhesives to improve flexibility, moisture resistance, and interfacial bonding between dissimilar materials. Additionally, serves as a crosslinker or chain extender in the synthesis of polyurethanes and hydrogels with tunable mechanical and degradation properties.
