  • Patent number: 11254904
    Abstract: A culture material including a 4-methyl-1-pentene polymer for cells, tissues, or organs, the culture material having a water contact angle at a culture surface of 50° to 100°, a sagging distance by a test method described below of 0 to 5 mm, and an oxygen permeation rate at a temperature of 23° C. and a humidity of 0% of 4500 to 90000 cm3/(m2×24 h×atm). A test piece having the same material as the culture material and the same thickness as the culture surface of the culture material and having a flat plate shape of 100 mm long and 10 mm wide is made. The test piece is fixed onto a test board in a state where the test piece protrudes lengthwise in a horizontal direction from a top surface of the test board, the top surface being horizontal.

  • Publication number: 20210087374
    Abstract: Provided is a cyclic olefin-based resin composition for molding containing a resin (A) which contains a structural unit (a1) derived from an ?-olefin and a structural unit (a2) derived from a cyclic olefin, has a glass transition temperature in both a region equal to or lower than 50° C. and a region equal to or higher than 125° C. in a case where the composition is subjected to differential scanning calorimetry, and has a dispersity within a range of 1.0 to 1.6 measured by gel permeation chromatography. Also provided is a molded product formed of the composition and the resin (A).
