Methods may include methods of producing polyester resin composition and methods of producing a polyester resin formed article that make it possible to improve thermal resistance, and to provide the polyester resin composition and the polyester resin formed article. Methods of producing a polyester resin composition may include: a step (I-a) of obtaining a polylactic acid composition (X) containing a polylactic acid (A), pentaerythritol (C), and a silicate (D); and a step (II-a) of mixing the polylactic acid composition (X) with a poly(3-hydroxyalkanoate) (B).

A biopolymer, which exists in a liquid phase at room temperature, a use thereof, and a preparation method therefor are provided.

Functionalized compounds including residues of one or more 1,1-disubstituted alkene compounds. Preferably the functionalized compound includes the residue of two or more 1,1-disubstituted alkene compounds, which are spaced apart. The functionalized compound may be produced by a transesterification reaction. The functionalized compounds may be employed in a polymerizable composition and may be used to prepare new polymers, (for example by reacting the alkene group).

Disclosed are graft copolymers, compositions including graft copolymers, intermediate materials, and related methods, where the graft copolymer includes a first polymer component including a 1,1-disubstituted-1-alkene compound (preferably a methylene malonate compound) and is grafted to a second component. The resulting graft copolymer may be hydrophilic or water soluble. The second component preferably is a hydrophilic component.

Compositions and methods for a hybrid biological and chemical process that captures and converts carbon dioxide and/or other forms of inorganic carbon and/or CI carbon sources including but not limited to carbon monoxide, methane, methanol, formate, or formic acid, and/or mixtures containing CI chemicals including but not limited to various syngas compositions, into organic chemicals including biofuels or other valuable biomass, chemical, industrial, or pharmaceutical products are provided. The present invention, in certain embodiments, fixes inorganic carbon or CI carbon sources into longer carbon chain organic chemicals by utilizing microorganisms capable of performing the oxyhydrogen reaction and the autotrophic fixation of CO.sub.2 in one or more steps of the process.
