Polyetherimide composition, method, and article

A resin composition, comprising:

• about 96 to about 99.95 weight percent of a polyetherimide;
• and
• about 0.05 to about 4 weight percent of an acidic additive selected from the group consisting of aliphatic carboxylic acids having a vapor pressure less than one atmosphere at 300° C., aromatic carboxylic acids having a vapor pressure less than one atmosphere at 300° C., and combinations comprising at least one of the foregoing acidic additives.

A resin composition, comprising:

• about 98 to about 99.95 weight percent of a polyetherimide;
• and
• about 0.05 to about 2 weight percent of octadecanoic acid.

A resin composition, comprising the reaction product of:

• a polyetherimide resin;
• and
• about 0.05 to about 4 weight percent of an acidic additive selected from the group consisting of aliphatic carboxylic acids having a vapor pressure less than one atmosphere at 300° C., aromatic carboxylic acids having a vapor pressure less than one atmosphere at 300° C., and combinations comprising at least one of the foregoing acidic additives.

A method of preparing a resin composition, comprising:

• blending a polyetherimide resin and an acidic additive selected from the group consisting of aliphatic carboxylic acids having a vapor pressure less than one atmosphere at 300° C., aromatic carboxylic acids having a vapor pressure less than one atmosphere at 300° C., and combinations comprising at least one of the foregoing acidic additives, to form an intimate blend.
