Anwendung

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

Hybrid biomaterials have been produced by the interaction of polyurethane oligomers with both fresh and glutaraldehyde-fixed porcine pericardium. The hybrid biomaterials so formed were translucent with occasional white streaks and/or spots, had increased stiffness (to touch) but remained pliable. No

Although biodegradation of model poly(ester-urethane)s and poly(ether-urethane)s has been demonstrated using a single enzyme system (cholesterol esterase (CE) in vitro, in vivo biodegradation most likely involves many processes acting together. In this study, the physical (film vs textured surface) and
