  The present invention relate to a novel silane coupling agent and a medical and/or dental curable composition comprising the same. It is an object of the present invention to provide a novel silane coupling agent that imparts high affinity to a radical polymerizable monomer, thereby imparting high mechanical strength, flexibility and durability when used for a medical and/or dental curable composition, and an inorganic filler surface-treated with the novel silane coupling agent and a novel medical and/or dental curable composition. A silane coupling agent including repeating units such as a urethane bond and polyethylene glycol (ether bond) at a specific position is used.

  In various embodiments, the present invention provides a functionalized thermoplastic polyurethane (TPU) containing bulk incorporated or surface-grafted quaternary ammonium compounds (QAC)s for contact-killing of a variety of microbes, where the QACs are on the surface of TPU to provide a sterile surface material that prevents bacteria commonly involved in device-associated infections (DAIs) from proliferating. The functionalized TPUs of the present invention can be formed into a wide variety of 3-dimensional shapes, such as catheters, medical tubing, laryngeal or tracheal stents, sutures, prosthetics, wound dressings, and/or a coating for medical devices and contains the residue of either a QAC containing diol monomer or an alkene functional diol monomer, which then allows the TPU to be functionalized with a QAC containing disulfide or free thiol compound, to form a quaternary ammonium functionalized thermoplastic polyurethane compound having antimicrobial properties for use in medical devices.

  在各种实施方式中，本发明提供了一种功能化的热塑性聚氨酯（TPU），其中包含大量引入或表面接枝的季铵化合物（QAC），用于接触杀灭多种微生物，其中QAC位于TPU表面，以提供一种无菌表面材料，防止通常涉及设备相关感染（DAIs）的细菌繁殖。本发明的功能化TPU可以形成多种三维形状，例如导管、医疗管、喉部或气管支架、缝合线、假体、伤口敷料和/或医疗设备的涂层，并包含含有二醇单体或烯功能二醇单体的QAC残留物，这使得TPU可以用含有二硫键或自由巯基化合物的QAC进行功能化，以形成具有用于医疗设备的抗菌性能的季铵功能化热塑性聚氨酯化合物。
