    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.

    Abstract: The present invention provides an olefin resin with an improved heat resistance, reduced stickiness, excellent optical and low temperature properties, as well as the balance between these physical properties. The olefin resin according to the present invention satisfies the following requirements: (I) a melting peak (Tm) is observed within the range of from 60° C. to 130° C., and the heat of fusion ΔH at the melting peak is within the range of from 5 to 150 J/g; (II) the percentage E (wt %) of a portion soluble in o-dichlorobenzene at 20° C. or lower, and the heat of fusion ΔH satisfy certain relationships; (III) the glass transition temperature (Tg) is from −80 to −30° C.; (IV) the spin-spin relaxation time (T2) of a component having the highest mobility, as obtained in a four-component approximation with a Lorentzian function performed for a free induction decay curve, is within the range of from 150 to 500 ms, and the abundance ratio of the component is within the range of from 15 to 50%; and (V) the intrinsic viscosity [η] as measured in decalin at 135° C. is within the range of from 0.1 to 12 dl/g.
