    摘要: A cable for transporting or distributing electric energy, especially medium or high voltage electric energy, includes at least one electrical conductor, at least one electrically insulating layer surrounding the electrical conductor, and at least one sheath surrounding the electrically insulating layer, wherein the sheath includes 65% to 95% by weight of at least one thermoplastic ethylene polymer; 5% to 35% by weight of at least one plasticizing agent, the percentages being expressed with respect to the total weight of the sheath. The above sheath guarantees improved flexibility without impairing mechanical properties and particularly thermopressure resistance, which is essential to preserve shape and integrity of the screen layer during cable installation and use at high operating temperatures.

    摘要: A synthetic material is disclosed, which is constituted by a copolymer of D, L-lactide and &egr;-caprolactone (which itself is characterized by lower degradation times than those obtainable with copolymers of L-lactic acid and &egr;-caprolactone), obtained by using as reaction control agent a sugar dianhyide with non-toxic characteristics. The use of suar dianhydrde in the reaction has a considerable control effect on the molecular weight of the copolymer and, thanks to its low molecular weight, this copolymer is characterized by extreraely short resorption times, in the order for the example of one or two months. The copolymer is used as covering clement to be placed around tendon sutures and/or nerve tracts with the aim of preventing formation of scarry adherences between the suture lines and the soft surrounding tissues.
