Non-volatile plasticizers and flow aids for polyesters

A method for reducing volatile emissions from polyester blends during drying comprising:

• a. providing a blend having:
• i. from about 1 to about 25 weight pphr of a poly(alkylene ether) having a number average molecular weight of from about 800 to about 6000 and represented by the formula:
• wherein:
• m is an integer of from 1 to 3;
• n is an integer of from 5 to 140;
• X is selected from the group consisting of hydrogen, hydrocarbon, and amide having 10 carbons or less;
• A and B are independently selected from the group consisting of alkyl, acyl, and aryl residues having from 1 to 200 carbon atoms;
• and
• ii. a semi-crystalline polyester resin having melting point greater than 200° C. selected from the group consisting of poly(ethylene terephthalate), poly(propylene terephthalate), poly(butylene terephthalate), poly(ethylene naphthalate), and poly(1,4-cyclohexanedimethylene terephthalate);
• and
• b. drying said polyester blend at a temperature greater than 100° C.
