Abstract:
The present invention provides an external lubricant composition for lead stabilized vinyl polymer. The external lubricant functions as both an external lubricant and a processing aid by speeding fusion and thus, obviates the need for a separate processing aid. The external lubricant comprises an effective amount for lubricating vinyl polymer of polyethylene having a Brookfield viscosity at a temperature of 150 DEG C of between about 1 000 and about 100,000 centipoises and an acid number as determined by standardized titration of KOH of between about 1 and about 40.
