preparation example Construction

[0238] [Preparation method of curable composition]

[0239] The preparation method of the composition of this invention is not specifically limited, A well-known method can be used. For example, after mixing each of the above-mentioned components, a curable composition can be prepared by stirring by a known method.

[0240] [cured product]

[0241] The cured product of the present invention is formed by curing the composition of the present invention described above. The shape of the cured product can be appropriately selected according to the application. Examples of the shape of the cured product include a powder form and a film form (film form), and among them, a film form is preferable.

[0242] When the cured product is formed into a film, the film thickness is not particularly limited, and may be, for example, 0.1 to 300 μm, more preferably 1 to 100 μm.

[0243] In addition, the cured product of the present invention includes a polymer compound including a repeating ...

Abstract

Provided is a curable composition that makes it possible to obtain a cured product having excellent adhesion to substrates and excellent biocompatibility. Also provided are a film and a cured producthaving excellent adhesion to substrates and excellent biocompatibility. Also provided is a medical member provided with the curable composition. The curable composition contains at least one betaine monomer selected from the group consisting of a compound represented by formula (1) and a compound represented by formula (2).

Description

technical field [0001] The present invention relates to a curable composition, film, cured product and medical parts. Background technique [0002] Artificial organs and medical devices are expected to be materials suitable for living organisms and made of materials that are not easily stained. For example, it is desired that substances introduced into the human body such as artificial blood vessels, catheters, stents, artificial bones, and dentures for a long period of time do not cause inflammation or rejection. Also, the replacement due to soiling causes a burden on the patient. Therefore, artificial organs and medical devices are desired to be formed of materials that have little interaction with living substances such as proteins, blood cells, and cells, that is, materials that are not easily adhered (bonded) to living substances. [0003] For example, Patent Document 1 discloses "a living material non-adhesive material comprising a polymer compound (A) containing a r...
