Application

Poly(tetrahydrofuran) (PTHF) can be used as a macroinitiator to prepare block copolymers via ring-opening polymerization.

Cross-linked PTHF can be used as a matrix to prepare thermally stable polymer electrolytes for lithium-ion batteries.

It can also be used as a starting material to prepare cyclodextrin-basedsupramolecular complexes for drug and gene delivery.

Aqueous dispersions of poly(ester-imide)s [P(E-I)s] have been prepared by dispersing the P(E-I)s in water without any external solubilizing agents. P(E-I)s were prepared from anhydride-terminated polyester prepolymer and diisocyanate. The -COOH groups in the polymer were then neutralized using triethylamine and
