Zusammenfassung: | PURPOSE:To improve both tension and elongation in a molten state and to obtain a corrugated pipe for wiring for electric power and telecommunication fields without fluctuation in strength by blow molding, by incorporating a melt tension improver in a vinyl chloride resin with a high degree of polymn. CONSTITUTION:A vinyl chloride resin compsn. for blow molding is provided by compounding 100 pts.wt. vinyl chloride resin with a high degree of polymn. (an average degree of polymn. of 900 or higher, most desirably 900-1,300) with 0.5-3 pts. molt tension improver (e.g. a methyl methacrylate polymer) and if necessary, 1-3 pts. auxiliary for improving impact strength (e.g. phthalates). |
