| Outline of Final Research Achievements |
The ring-opening polymerization of lactide by using a diol with a tertiary amino group followed by chain-extension with diisocyanate gave poly(lactide-urethane)s with equally spaced tertiary amino groups. Treatment of the poly(lactide-urethane)s with iodomethane afforded the polymers with quaternary ammonium groups. Ionization of the polymers was found to enhance their tensile modulus and to decelerate their biodegradation. Similar poly(ε-caprolactone-urethane)s with quaternary ammonium groups and poly(lactide-urehtane)s with carboxylate groups were synthesized and their properties were evaluated.
