Disclosed are compositions comprising polyesters containing a chain of residue of: diols and diesters along the chain, wherein at least a portion of the diesters are 1, 1-diester-1-alkenes, and the chains have alkene groups incorporated into the chains; the composition comprising one or more of the following: i ether groups derived from alcohols, diols, polyols, or a combination thereof obtained via Michael addition to the alkene groups and a residue of the alkene groups remaining after Michael addition; ii the formed polyesters contain one percent or less of residual 1, 1-diester-1-alkene which are unreacted; iii one or more free radical inhibitors; and iv a stabilizer comprising one or more of: oxo acids phosphorous or esters thereof, aluminum sulfate, stannous pyrophosphate, stannous sulfate, aluminum dihydrogenphosphate or decomposition products thereof. The stabilizer is present in an amount sufficient to enhance stability of the polyester without lowering reactivity of the polyester.

The present invention provides a low molecular mass PPF polymer (and related methods) that is suitable for 3D printing and other polymer device fabrication modalities and can be made inexpensively in commercially reasonable quantities. These novel low molecular mass PPF polymers have a low molecular mass distribution (.sub.m) and a wide variety of potential uses, particularly as a component in resins for 3D printing of medical devices. The ability to produce low .sub.m PPF creates a new opportunity for reliable GMP production of PPF. It provides low cost synthesis and scalability of synthesis, blending of well-defined mass and viscosity PPF, and reduced reliance on solvents or heat to (a) achieve mixing of 3D printable resins or (b) and flowability during 3D printing. These PPF polymers are non-toxic, degradable, and resorbable and can be used in tissue scaffolds and medical devices that are implanted within a living organism.

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).

This invention relates to a process for preparing succinic acid and succinate ester from a succinic acid salt in fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce succinic acid through biological fermentation. The succinic acid salt in the fermentation process is subjected to double displacement reaction with a strong acid leading to release of succinic acid. Succinic acid is recovered by fractional crystallization integrated with simulated moving bed chromatography to produce succinic acid and succinate ester.

The invention provides an adhesive coating material which realizes excellent adhesive strength and moist-heat resistance at the time of bonding a solar cell sealing material and a base sheet, a polyol composition for the coating material, a cured object of the adhesive coating material, an adhesive sheet obtained by being coated with adhesive coating material, and a solar cell module using the sheet. As a polyol component of the adhesive coating material which forms an adhesive layer b in a back sheet E of the solar cell module illustrated in Figure, a hydroxyl group-containing (meth)acrylic resin (I) and unsaturated double bond-containing polyester polyol (II) are used as essential components.
