Original Abstract

Oligo-[(R)-3-hydroalkanoates] (OHA) are biobased and biodegradable oligomers that can serve as building blocks in polymer synthesis and can find use in areas such as medicine, material science or cosmetics. However, the oligomers are usually prepared via multi-step and time-consuming methods with limited scalability that restricts their wider use. More direct methods for preparing OHA from bacterial poly-[(R) -3-hydroxyalkanoate] (PHA) using alkaline agents have been investigated. Preparation by alkaline degradation of the polymer in aqueous solution was successful, but very time consuming. Preparation by thermal degradation of the polymer proved to be more effective. It was possible to advantageously use technical-grade PHA, which contained a pro-degradative impurities, or directly bacterial biomass treated with a catalytic amount of hydroxide.
