Description

Application

• Thermoresponsive Random Poly(ether urethanes) with Tailorable LCSTs for Anticancer Drug Delivery.: This study explores the development of thermoresponsive random poly(ether urethanes) synthesized using Isophorone diisocyanate. These polymers exhibit adjustable lower critical solution temperatures (LCSTs), making them suitable for controlled anticancer drug delivery applications. The research highlights the potential of Isophorone diisocyanate in creating advanced materials for medical use, specifically in drug delivery systems (Sardon et al., 2015).
