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 18):
