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 an ethylene vinyl acetate vinyl chloride graft copolymer with a specific amount of a polyester adhesive resin. CONSTITUTION:(A) 100pts.wt. ethylene vinyl acetate vinyl chloride graft copolymer containing 40-70wt.%, preferably 45-60wt.% vinyl chloride and 5-40wt.%, preferably 10-30wt.% vinyl acetate is blended with (B) 10-60pts.wt., preferably 20-50pts.wt. ester adhesive resin to give a watertight mixture having 5-150, preferably 15-60 melt index. |
