Abstract: The present invention relates to a cable comprising a crosslinked layer obtained from a polymer composition, the polymer composition comprising: a polymer blend comprising an ethylene vinyl acetate (EVA) copolymer, nitrile rubber (NBR), and an ethylene-methyl acrylate (EMA) copolymer; a crosslinking agent; and a flame-retardant filler.

Abstract: A cable is provided having at least one elongated conductor surrounded by at least one cross-linked layer, said layer being obtained from a polymer composition comprising a polymer, a crosslinking agent, and an amine as co-crosslinking agent, wherein said amine has a nucleophilic value (N) of 14 or more.

Abstract: A cable for power transmission or communication has a core unit having at least one conductor and an insulating layer surrounding each conductor. A first shielding layer surrounds the core unit and is formed of a polymer-carbon composite in which carbon-based particles are dispersed in a matrix of thermosetting polymer material, the first shielding layer having an electrical resistance of 10 ?·m or less. A metal-based second shielding layer surrounds the first shielding layer.

Abstract: A hyperbranched polyetherketone and a heat-resistant blend of polyvinylchloride with the same. The polyethereketone is synthesized by self-polycondensation of 3,5-bis[4-[(2,3,4,5,6-pentafluorophenyl)carbonyl]phenoxy]-4-hydroxbenzophenone or 3,5-difluoro-4-hydroxybenzophenone, and then substituting 50 to 80 mole % of fluorine atoms present in the side chains and ends of the PEK molecule by polar groups. In addition, a blend of polyvinylchloride can be manufactured using the hyperbranched polyetherketone by a melt blending technique applicable for industrial purpose at a temperature of 180 to 120° C., and thus the blend of polyvinylchloride with the polyetherekentone can be applied to high temperature end-use products such as hot water pipes.
