Abstract:
The invention relates to stabilizer compositions for polymers such as polyolefin polymers, which decrease a phosphorus based stabilizer content necessary to stabilize the polymer. The premixed stabilizer compositions include an antacid, an organic acid-metal salt, and a primary antioxidant such as a sterically-hindered phenolic compound, a sterically-hindered amine compound, a hydroxylamine compound, and combinations thereof. The premixed stabilizer may further include a portion of the phosphorus based stabilizer content necessary to stabilize the polymer. The invention also relates to a method for the preparation of the stabilized polymer compositions provided by the use thereof.

Claim (Index 21):
The stabilized polymer composition according to  claim 14 , wherein the stabilized polymer composition is provided by a process comprising:\n (1) preparing a first premixture comprising the antacid (a) and the organic acid-metal salt (b) or the primary antioxidant (c); (2) intimately mixing the first premixture obtained from step (1) at an elevated temperature sufficient to provide a molten mixture comprising a dispersion of the antacid (a) in the organic acid-metal salt (b) or the primary antioxidant (c) or both; (3) optionally, lowering a temperature of the molten mixture to provide a second premixture in solid form; and (4) combining the molten mixture of step (2) or the second premixture in solid form of step (3) with the polymer and at least one additional ingredient of (b) or (c), if not already present.
