摘要： Telecommunication cable having an elongated element housing at least one transmitting element. The elongated element has a water-soluble polymeric composition of a vinyl alcohol/vinyl acetate copolymer having a saponification degree of about 60% to about 95%; a plasticizer; a hydrolysis stabilizer compound having a chelant group having two hydrogen atoms bonded to two respective heteroatoms selected from nitrogen, oxygen and sulfur. The two hydrogen atoms have a distance between each other of 4.2×10−10 m to 5.8×10−10 m. The stabilizer compound is present in an amount of at least 0.75 mmoles per 100 g of copolymer. The elongated element is in particular a buffer tube housing a plurality of optical fibers. The presence of the stabilizer reduces the increase of the hydrolysis degree of the copolymer upon aging, thus maintaining the desired water blocking properties of the copolymer.

摘要： A process for manufacturing a water-resistant telecommunication cable. The cable has a solid and compact element having a water-soluble polymer material having vinyl alcohol/vinyl acetate copolymer having a hydrolysis degree of 60-95% and a polymerisation degree higher than 1,800 and at least one solid low-melting and one solid high melting plasticizers. The process produces continuously the water-soluble polymer material by separately feeding, in sequence, a multi-screw extruder, in the flow direction, with the copolymer and the high melting plasticizer melting and mixing them while transporting them through the extruder, and with the low melting plasticizer, melting and mixing them with the copolymer and the high melting plasticizer, subsequently homogenizing the copolymer and the plasticizers and finally discharging the melt, at a temperature lower than or equal to 205° C. A process for extruding the above PVA based water-soluble polymer material. The process allows extrusion of PVA with an enhanced productivity and reproducibility requiring shorter times for absorbing the plasticizers onto the polymer.
