    Abstract: Various embodiments of a process for making fibers comprising a high heat polymer are provided. In one embodiment, a process for producing polymer fiber includes extruding molten polymer having a melt temperature ranging from about 180-500°C, passing the molten polymer through a plurality of openings of a spinneret to produce a fiber bundle, and contacting the fiber bundle with a cooling medium having a substantially uniform flow distribution across the width of the fiber bundle where the cooling medium has a temperature that ranges from about 0°C to about 80°C.

    Abstract: A continuous process of making polyetherimide foam materials and articles that include these foam materials. The continuous process is a foam extrusion process that uses selected blowing agents, equipment design and processing conditions to continuously produce extruded foam with a substantially uniform cell size in a wide range of cell densities. Subsequent heating may be used in certain embodiments to remove any residual components from the foam, such as any blowing agents or nucleating agents. Due to the greater densities as well as the characteristics inherent in polyetherimide articles, the resulting foam materials are suitable for a much broader range of applications. The continuous process provides a more cost effective product while also avoiding the use of Freon and/or other agents potentially harmful to the environment.
