摘要
Articles comprising at least one polyester polymer melt phase product comprising at least one polyethylene terephthalate polyester; at least one metal compound chosen from alkali metal-aluminum compounds; and from 5 ppm to 1000 ppm of at least one phenolic stabilizer. Also provided is a melt phase process for making a polyester polymer melt phase product comprising: forming a slurry comprising at least one glycol chosen from ethylene glycol and derivatives of ethylene glycol and at least one acid chosen from terephthalic acid and derivatives of terephthalic acid; adding 5 ppm to 1000 ppm of at least one phenolic stabilizer; and reacting said at least one glycol and said at least one acid in the presence of at least one catalyst chosen from alkali metal-aluminum catalysts.
