Abstract: A cellulose ester film containing a polyester represented by Formula (1) or (2), wherein an in-plane retardation value (Ro) is 0 to 5 nm and a retardation value in a thickness direction (Rt) is ?20 to 10 nm, Ro and Rt being measured at 23° C. and 55% RH: B1-(G-A-)mG-B1??Formula (1) wherein B1: monocarboxylic acid, G: dihydric alcohol, A: dibasic acid, B1, G and A contain no aromatic ring, m: repeat number, plural B1 may be the same or different, and plural G may be the same or different; and B2-(A-G-)nA-B2??Formula (2) wherein B2: monoalcohol, G: dihydric alcohol, A: dibasic acid, provided that none of B2, G and A contains an aromatic ring, n: repeat number, plural B2 may be the same or different, and plural G may be the same or different.

Abstract: Provided is a collagen-cellulose material containing, based on a total weight of the collagen-cellulose material: 1.0-9.0 wt. % of a collagen; 0.2-3.0 wt. % of cellulose or a derivative thereof; 0.5-6.5 wt. % of at least one acid selected from an inorganic acid, an organic acid, and mixtures thereof; and water. Also provided is a process for producing the collagen-cellulose material. Also provided is an artificial blood vessel containing the collagen-cellulose material which is in the form of a hollow tube, an artificial tissue containing the collagen-cellulose material which is in the form of a sheet, and an artificial bone containing the collagen-cellulose material which is in the form of a solid. Also provided is a medical device containing the collagen-cellulose material, as well as a process for testing phlebotomical, surgical or orthopedic instrumentation or practicing phlebotomical, surgical or orthopedic procedures using the medical device containing the collagen-cellulose material.

Abstract: Disclosed herein is a thermoplastic cellulosic composition for preparing a cellulose-based masterbatch and/or a cellulose-based fiber with a networked structure. In one example, the thermoplastic cellulosic composition includes an esterified cellulose present in a range of about 80 wt % to about 95 wt %, polyethylene glycol present in a range of about 4.5 wt % to about 12 wt %, a tri-functional cross-linking agent present in a range of about 0.01 wt % to about 3 wt %, an initiator present in a range of about 0.01 wt % to about 0.15 wt %, and a dispersing agent present in a range of about 0.01 wt % to about 5 wt %.

Abstract: A cellulose ester film comprising a cellulose ester and a compound containing: an acrylate group or a methacrylate group; and a phenolic hydroxyl group, in the molecule.
