Abstract: Disclosed is a polyester resin composition for a covering material of a cable. The present invention provides the polyester resin composition for a covering material of a cable including a polyester resin as a base resin, including 0.1 to 4 parts by weight of amide-based wax as an internal lubricant, based on 100 parts by weight of the polyester resin as the base resin. The polyester resin composition according to the present invention has advantages that the resin may be uniformly and completely melted using only the general equipments such as an extruder with an L/D ratio of less than 30 and a single-stranded screw without an additional investment for equipments, and also has such an improved processability that protrusions are minimized upon forming a covering layer of a cable, as well as an excellent mechanical properties such as tensile strength, elongation, etc.

Abstract: Disclosed is the preparation of organic/inorganic hybrid particles comprising magnesium hydroxide cores and tethered copolymer chains whose composition can be selected to allow dispersion in targeted plastic materials, thereby providing improved mechanical, electrical and flame retardant properties. Processes for preparing the same are also disclosed.
