Abstract
Disclosed is a process of coating discrete, unagglomerated particles of less than 20 microns with a high polymer coating, and compositions such as conductive compositions using such coated particles. The particles are coated with the polymer in a fluid energy mill such that substantially uniform coated particles are obtained which are free-flowing, non-agglomerative and readily dispersable in a suitable binder.
