Disclosed is a process for treating olefin polymer particles with phosphite- and phosphonite-free compositions consisting essentially of: A. a polyhydric alcohol ester of a hindered phenol derivative of propionic acid having a melting point or melting range below about 130 DEG C., B. about 20 to 35 parts based on 100 parts by weight of component A of a mono-ester of a hindered phenol derivative of propionic acid having a melting point or melting range below about 130 DEG C., C. about 20-75 pph of a viscosity-reducing agent having a viscosity of about 180 to 55,000 Saybolt Universal Seconds at 100 DEG F. (38 DEG C.), D. up to 1000 pph each of an antistatic agent, a slip agent or mixture thereof and E. up to 1000 pph each of a light stabilizer, a thioether, an organic polysulfide, an acid scavenger or neutralizer, a nucleating agent, or a mixture thereof. The resulting surface-treated polymer particles and end uses therefor are also disclosed. |
