摘要

The present invention involves the preparation and use of polyester blend containing at least one acid terminated polyamide which give the improved color as compared to the prior art. The present invention comprises polyester blend composition having improved color comprising: (A) about 99.98 to about 95 weight percent of a polyester which comprises (1) a dicarboxylic acid component comprising repeat units from at least 85 mole percent terephthalic or naphtalhene dicarboxylic acid; and (2) a diol component repeat units from at least 85 mole percent ethylene glycol, based on 100 mole percent dicarboxylic acid and 100 mole percent diol; and (B) acid terminated polyamide.
