摘要：
A process is described which reduces the amount of bloom and/or plate-out of phosphite antioxidants during polymer processing by the addition of at least one polyethylene glycol (or blends thereof) or polycaprolactones (or blends thereof) having an average molecular weight of approximately 1,000 to 20,000, most preferably between 4,000 to 10,000.
