Application

Diethylene glycol (diglycol) is used in biomaterials engineering to functionalize peptide nanofibers to improve their aggregation and proteolytic degradation properties. Diethylene glycol may be used as a solvent, reducing agent and derivatizing agent in the preparation of various types of nanoparticles.

Renewable ABA triblock copolymers were prepared by sequential polymerization of the plant-based monomers menthide and α-methylene-γ-butyrolactone (MBL or tulipalin A). Ring-opening transesterification polymerization of menthide using diethylene glycol as an initiator gave α,ω-dihydroxy poly(menthide) (HO-PM-OH), which was converted to α,ω-dibromo...
