-23- ABSTRACT OF THE DISCLOSURE A process for the preparation of free flowing pellets from tacky, cold flowing polymers is provided. The process includes the steps of adding a non-cold flowing rubber to a tacky, cold flowing polymer to form a blend, forming pellets of the blend and then subjecting the pellets to a surface treatment to remove tack. The pellets are thereafter separated and can be washed and dried to yield a free flowing material. A novel polymer blend, which ex- hibits free flow in small particles is also provided which comprises from about 55 to 95 parts of a tacky, cold flowing, polymer and from about 5 to 45 parts of a non-cold flowing rubber wherein tack contributed by the cold flowing polymer is removed at the surface of the particles.
