The present invention provides a master batch composition for environmentally degrading conventional plastics including a carrier resin, at least one oxidative degradant, at least one nature biodegradable degradant and at least one foaming agent. The present invention also provides a plastic product which is environmentally degradable at a very low cost versus conventional bio-sourced plastics, and has broad applications for single-use disposable applications or for short-lived products that are discarded within two years of manufacture.

The present invention generally provides implantable articles and methods of forming implantable articles from a crosslinked ultrahigh molecular weight polyethylene (“UHMWPE”) blend stabilized with Vitamin E. The crosslinked UHMWPE blend may be prepared by combining the UHMWPE material and vitamin E prior to irradiating the UHMWPE blend with electron beam radiation at a sufficient radiation dose rate to induce crosslinking. The crosslinked UHMWPE blend may be incorporated into a variety of implants, and in particular, into endoprosthetic joint replacements

A water soluble polymer blend composition includes at least one water soluble polymer and at least one immiscible polymer. The water soluble polymer and the immiscible polymer can be melt processed at a temperature above their respective melt processing temperatures and quenched to form the water soluble polymer blend composition in a non-equilibrium state, such that it can exhibit a non-equilibrium morphology. Non-equilibrium morphologies can include, e.g., a microfiber morphology or a co-continuous morphology.

A shear-thinning hydrogel composition includes: a first polymer chain including: (i) a first plurality of units each having at least one of a monosaccharide and an amino acid; and (ii) a cross-linking group bound to the at least one of the monosaccharide and the amino acid of one of the first plurality of units via conversion of a carboxyl group of the unit to a peptide bond; a second polymer chain including a second plurality of the units; and a cross-linking additive connecting one of the second plurality of units to the first polymer chain via the cross-linking group.

The present disclosure relates to a composition for a crosslinking agent for the preparation of a sensing layer or a diffusion control layer of an electrochemical biosensor comprising genipin or a derivative thereof, in which due to the properties of genipin that can be extracted and used from plants, not only it has high biocompatibility compared to conventional crosslinking agents with high toxicity, but also it can easily confirm the progress of the reaction by measuring UV or measuring the amount of amine groups present when reacting with a compound having an amine group, for example, an electron transport medium, and additionally, it has the advantage of suppressing a rapid decrease in sensor life due to high concentration of glucose while maintaining an appropriate sensitivity to glucose.
