Abstract: Resorbable implants, coverings and receptacles comprising poly(butylene succinate) and copolymers thereof have been developed. The implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing molding, pultrusion or other melt or solvent processing method. The implants, or the fibers preset therein, may be oriented. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings, receptacles and implants described herein, may be made from meshes, webs, lattices, non-wovens, films, fibers, foams, molded, pultruded, machined and 3D printed forms.

Abstract: A composition includes a polyester urethane. The polyester urethane includes a crosslinker based on diisocyanate and an alternating copolymer resin of polyol and polyacid. The resin has a degree of branching, weight average molecular weight, polydispersity index, and viscosity prior to the crosslinking. The polyester urethane has a microstructure of hard segments and soft segments based on a selected combination of polyol, polyacid, degree of branching, the weight average molecular weight, the polydispersity index, the viscosity, the diisocyanate, the first stoichiometric ratio, and the second stoichiometric ratio. The microstructure provides a predetermined property to the composition selected from a degradation rate in an aqueous environment, release rate of a drug loaded in the polyester urethane in the aqueous environment, solubility of the drug, and combinations thereof.

Abstract: Provided is an aliphatic polyester composition. The aliphatic polyester composition comprises a polybutylene succinate, wherein the proton nuclear magnetic resonance of the aliphatic polyester composition has a first characteristic peak and a second characteristic peak. The first characteristic peak is located between 3.84 ppm and 4.32 ppm, and the second characteristic peak is located between 5.65 ppm and 5.85 ppm. The integral value of the first characteristic peak is set to be 100 and the integral value of the second characteristic peak is less than 0.10. By controlling the integral value of the second characteristic peak in H1-NMR of the aliphatic polyester composition, the aliphatic polyester composition has good appearance and low concentration of carboxylic acid end group and thereby the product value thereof is increased.

Abstract: A wearable device including a body having one or more embedded electronic components, the body further including a thermoset material having a polymeric backbone with at least one urethane linkage and a glass transition temperature. At a first temperature that is lower than the glass transition temperature, the body has an original shape. When the body is heated to a second temperature that is higher than the glass transition temperature, the body is deformable from the original shape to a first shape and when the body is cooled to a third temperature that is lower than the glass transition temperature, the first shape is maintained. The body is further configured to transition from the first shape to the original shape when the body is heated from the third temperature to a fourth temperature that is higher than the glass transition temperature.

Abstract: The present invention provides a decanedioic acid produced by microbial fermentation process, in which the content of C10 aliphatic acid and C10 hydroxy aliphatic acid is maintained at a very low level. The present invention also provides a preparation method of the decanedioic acid and a polymer prepared by using the decanedioic acid as monomer. The decanedioic acid provided by the present invention is prepared by microbial fermentation process. The decanedioic acid product which is produced through the processes of microbial fermentation and separation has a higher purity, a higher thermal stability, and a lower impurity content. The decanedioic acid provided by the present invention could satisfy the requirements of high grade product of polyamide or polyester to produce polymer with excellent qualities. The preparation method of the decanedioic acid provided by the present invention which has many advantages of mild reaction conditions, environmental friendliness, high yield, and good product quality, may replace the chemical method to be used in industrial scale production of the decanedioic acid.
