Abstract:
1. A water-resistant telecommunication cable comprising a longitudinal cavity extending along the length of the cable and a solid and compact element housing at least one transmitting element, wherein the solid and compact element is associated with the cavity and comprises a water-soluble polymer material comprising: a vinyl alcohol/vinyl acetate copolymer having a hydrolysis degree of about 60% to about 95% and a polymerisation degree higher than about 1,800; at least a first solid plasticizer, having a melting point between 50° and 110° C., and a second solid plasticizer, having a melting point equal or higher than 140° C., in an amount of about 10–30 and 1–10 parts by weight per hundred parts by weight of the copolymer, respectively; the water-soluble polymer material showing: a complex modulus (G*) equal or higher than 2.5 10 a ratio of the viscous modulus to the elastic modulus (tan δ) equal or lower than 2.30; and a glass transition temperature (Tg) of about 20° to about 35° C.
