A resin composition comprises a prepolymer, a reactive diluent, and optionally a crosslinker, wherein the reactive diluent has an absorption maximum (Amax) or excitation maximum (Amax) of between 350 and 520 nm for example in acetone and at pH 7.

Disclosed herein is a method for producing a thermally stable thermoplastic polyoxazolidinone compound including the steps of mixing (a) at least one diisocyanate, (b) at least one organic compound having two epoxide groups, (c) at least one catalyst, catalyzing the formation of oxazolidinone groups and (d) optionally at least one solvent to form a polyoxazolidinone, and contacting this polyoxazolidinone with carbon dioxide. Further disclosed herein are a thermoplastic polyoxazolidinone, obtained from the disclosed method, a method for producing a molded part including the step of melting the polyoxazilodinone, introducing the melt into a mold, cooling the polyoxazolidinone in the mold to temperatures below its melting point and demolding the obtained molded part, and a molded part obtained by such a method.

The present invention relates to a supramolecular biodegradable polymer comprising a quadruple hydrogen bonding unit (abbreviated herein as 4H-unit), a biodegradable backbone and hard blocks and a process for preparing such a supramolecular biodegradable polymer. The supramolecular polymer is specifically suitable for biodegradable articles such as biomedical implants that need high strength and/or elasticity, e.g. medical implants in the cardio-vascular field.

An isocyanate reactive composition comprising At least one component selected from the group consisting of an isocyanate reactive component; a treating agent selected from the group consisting of cyclic urea substituted with at least one isocyanate reactive group, a free radical scavenger, or a polymer acid, or a mixture thereof; one or more amine components, each of said amine components having a given structure.

Provided are a self-healing polyurethane (PU) material, a double-layer self-healing PU film, and a preparation method and use thereof. In the disclosure, the self-healing PU material includes a PU material I and a PU material II that are packaged separately. A soft-layer PU film prepared based on the PU material I and a hard-layer PU film prepared based on the PU material II could be combined to form a double-layer PU film.
