A low-temperature processable aliphatic polyester having 3-hydroxybutryates (3HB) and 4-hydroxybutyrates (4-HB) as basic repeated structures and an adjusted content of 4-hydroxybutyrates (4HB) is described. Articles based on the aliphatic polyesters are described and include a biodegradable wax, a medical device, a low-temperature hot melt, a non-woven cloth, a bioplastic, a drug carrier, a medical wrap, a medical fiber, a medical filament, a medical stent, or an orthopedic prosthesis. Methods for preparing the aliphatic polyesters are described.

The patent application relates to a method of producing a monomer component from a genetically modified polyhydroxyalkanoate (PHA) biomass, wherein the biomass is heated in the presence of a catalyst to release a monomer component from the PHA.

Process for producing a monomer component from a genetically modified polyhydroxyalkanoate biomass

Processes and methods for making biobased gamma-butyrolactone from renewable carbon resources are described herein.

Process for gamma-butyrolactone production

This invention relates to single solvent polymer extraction methods.

Single solvent polymer extraction methods

A method of isolating a PHA, includes combining the PHA, a first solvent and a second solvent to form a combination, the first solvent being capable of forming an azeotrope with the second solvent; and heating the combination to form the azeotrope of the first and second solvents.

The present invention provides methods for isolating a PHA. The method comprises combining the PHA, a first solvent and a second solvent to form a combination, the first solvent and the second solvent being capable of forming an azeotrope with the second solvent; and heating the combination to substantially remove the first solvent from the combination. Alternatively, the method comprises combining the PHA, a first solvent, a second solvent and a third solvent to form a combination, the first solvent and the second solvent being capable of forming an azeotrope with the third solvent; and heating the combination to substantially remove the first solvent and the second solvent from the combination.
