Abstract

A method of making a hydroxyl-terminated thioketal diol is provided, the method comprising reacting a thioketal ester with a non-pyrophoric reducing agent to form a hydroxyl-terminated thioketal diol. The hydroxyl-terminated thioketal diol can be 2,2-(propane-2,2-diylbis(sulfanediyl)) diethanol. The non-pyrophoric reducing agent can be a sodium aluminum hydride, for example, sodium bis(2-methoxyethoxy)aluminum hydride. The thioketal ester can be dimethyl 2,2-(propane-2,2-diylbis(sulfanediyl)) diacetate. A biodegradable matrix prepared by reacting a hydroxyl-terminated thioketal diol with an isocyanate is provided. A method of making a biodegradable polyurethane composite is also provided.
