<p><P>PROBLEM TO BE SOLVED: To provide a vinyl chloride based resin compound using a crushed product of power cable protecting ducts collected in the city, having excellent extrusion stability, a good appearance and excellent heating compression performance and exhibiting stable impact resistance and a power cable protecting duct using the compound. <P>SOLUTION: The resin compound comprises 3-10 wt.% of an acrylic copolymer having a glass transition temperature equal to or higher than -140°C and lower than 0°C which is produced from 100 pts.wt. of a (meth)acrylate and 0.1-10 pts.wt. of a polyfunctional monomer, 40-99 wt.% of a vinyl chloride based graft copolymer formed by 90-97 wt.% graft copolymerization of a vinyl chloride based vinyl monomer and 1-60 wt.% of a crushed product of power cable protecting ducts made of a vinyl chloride based resin and collected in the city. The crushed product is characterized in that the fraction of a specific gravity of≤0.2 generated in a process of crushing the power cable protecting ducts has been removed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
