The external lubricant comprises an effective amount for lubricating vinyl polymer of polyethylene having a Brookfield viscosity at a temperature of 150.degree. C. of between about 1000 and about 100000 centipoises and an acid number as determined by standardized titration of KOH of between about 1 and about 40.
