ABSTRACT:
Disclosed herein is a thermoplastic polymer composition comprising a blend of a thermoplastic polymer admixed with from about 5 to 50 ppm black iron oxide particles, based on the amount of said thermoplastic polymer. The black iron oxide is admixed with the polymer in order to speed up the process of reheating parisons formed from the polymer during bottle manufacturing. The composition has the beneficial combination of a large percent reheat rate improvement (RIV) with only a small decrease in transparency (.DELTA.L*). The ratio of RIV/.DELTA.L* is significantly better than carbon black--polymer blends having similar RIV.
