Abstract: Compositions and methods for producing compositions comprising a monoamine-endcapped polyimide component. Based on a gas chromatography mass spectroscopy analysis of a surface rinse of the composition performed at room temperature, the composition can have at least one surface with less than or equal to 5 ppb releasable phosphorous residuals, and less than or equal to 5 ppb releasable volatile organic compound residuals. The composition can also comprise less than or equal to 10 ppb combined releasable residuals. Because of the very low levels of residual contamination, the compositions can be used to produce a variety of articles including a disk drive.
