The content of the carboxyl group is such that the acid value is in the range of 10 to 20 mgKOH, and if it deviates from this range, the effect of the present invention may not be exhibited. The oxidized polyethylene wax has an increased affinity with the chlorinated vinyl chloride resin due to the carboxyl group, and coats the surface of the molecules of the chlorinated vinyl chloride resin in a molten state with a carboxyl moiety.
Further, the carboxyl group has a strong affinity for a metal and has a property of coating the surface of a mold. In the present invention, the effect of the present invention is achieved only by using two kinds of oxidized polyethylene waxes having different weight average molecular weights, and the weight average molecular weight is 2,000 to 40.
