Abstract: Disclosed is a process for controlling the amount of transesterification taking place during solid stating of poly(ethylene terephthalate) of poly(ethylene naphthalenedicarboxylate) blends to a desirable level, e.g., 5-20 %, by addition of an effective amount, e.g., at least 0.25 weight %, of a phosphorous stabilizer such as bis(2,4-di-t-butylphenyl)pentaerythritol diphosphate. Also disclosed are polymer blends containing the phosphorous stabilizer.
