PURPOSE:To obtain a watertight mixture suitable as a watertight filler for vinyl chloride insulated wire, having excellent bond strength to vinyl chloride resin and conductive metal, by blending a vinyl acetate vinyl chloride copolymer with a specific amount of a polyester adhesive resin. CONSTITUTION:100pts.wt. vinyl acetate vinyl chloride copolymer containing 70-95wt.%, preferably 80-90wt.% vinyl chloride is blended with 10-60pts.wt., preferably 20-50pts.wt. ester adhesive resin to give a watertight mixture having 5-150, preferably 15-60 melt index. |
