Most polyolefins require both free radical stabilization and acid neutralization. Conventional formulating follows a process of independent selection for stabilizers and neutralizers. This study shows that the use of a full factorial statistical design can facilitate concurrent optimization of neutralizer and stabilizer. A fractional factorial design did not provide sufficient information. Calcium lactate was shown to effectively improve YI color as well as neutralize acid residues.
