    摘要： A medical tubing of a random copolymer containing an olefin-based monomer, such as ethylene, in an amount of 50-95 mol % and, preferably 75-95 mol %, and a styrene-based monomer, such as styrene, in an amount of 50-5 mol %, preferably 25-5 mol %. The medical tubing can be used as a conjugating tube or a connecting tube of medical equipment such as infusion circuits and blood circuits, and for administering an oil-soluble drug such as nitroglycerin. The random copolymer does not contain chlorine atoms or a plasticizer. The tubing has very small adsorption of the drugs, can withstand squeezing action by an infusion pump, has a possibility of undergoing null-ray sterilization and has flexibility necessary for clinical use.

    摘要： Disclosed herein is an olefin copolymer shrink film comprising an &agr;-olefin/aromatic vinyl compound random copolymer. This &agr;-olefin/aromatic vinyl compound random copolymer comprises 99.9 to 58 mol % of structural units derived from ethylene, 0 to 30 mol % of structural units derived from an &agr;-olefin having 3 to 20 carbon atoms (provided that the total of the structural units derived from ethylene and the structural units derived from an &agr;-olefin having 3 to 20 carbon atoms ranges from 99.9 to 88 mol %), and 0.1 to 12 mol % of structural units derived from an aromatic vinyl compound. The &agr;-olefin/aromatic vinyl compound random copolymer has an intrinsic viscosity [&eegr;], as measured in decalin at 135° C., of 0.1 to 10 dl/g and has a melting point, as measured by a differential scanning calorimeter, of 60 to 125° C. The olefin copolymer shrink film is oriented in at least one direction. The olefin copolymer shrink film has excellent low-temperature shrinkability and transparency.
