ADDITIVE PRODUCTION PROCESS WITH A THERMOPLASTIC RADICALLY CROSS-LINKABLE CONSTRUCTION MATERIAL

The present invention relates to a method for producing an object in an additive manufacturing process from a precursor and comprises the following steps: I) depositing a layer of a radically cross-linkable construction material, which corresponds to a first selected cross-section of the precursor, on a carrier; II) depositing a layer of a radically cross-linkable construction material, which corresponds to a further selected cross-section of the precursor, on a previously applied layer of the radically cross-linked construction material; III) repeating step II) until the precursor is formed. The radically cross-linkable construction material comprises a thermoplastic radically cross-linkable polyurethane with a urethane group content of 5% by weight and a photoinitiator. The radically cross-linkable construction material is also heated to a processing temperature that is greater than the melting point of the radically cross-linkable polyurethane. After step III) the precursor having a temperature of 20 C. is defined as the object, or step IV) is performed: IV) performing a chemical reaction in the precursor obtained after step III) so that the object is obtained.

ANTIBACTERIAL HYDROPHILIC COMPOUND AND USE THEREOF

The present disclosure provides an antibacterial hydrophilic compound. The antibacterial hydrophilic compound may react, induced by light through a hydrogen abstraction group in the structural formula thereof, with a CH group and thus bind to a surface of a material having the CH group (for example, chemical fibers such as polyester, chinlon, and the like; plastics, rubbers, and other similar materials), which can impart a durable antibacterial activity and hydrophilicity to the material. The antibacterial hydrophilic compound has a relatively strong binding force to the surface of the material without damaging the mechanical properties of the raw material. The present disclosure also provides a modified material that is modified by the antibacterial hydrophilic compound.

NICOTINYL ALCOHOL ETHER DERIVATIVE, PREPARATION METHOD THEREFOR, AND PHARMACEUTICAL COMPOSITION AND USES THEREOF
