Abstract:
The disclosure defined by this invention provides a method for extruding thermoplastic polymers which includes the step of creating high pressure steam in the extruding apparatus so as to prevent scorching and to solubilize contaminants. The method can be used in a neutralization step of ionomers in an extrusion process to obtain an extrudate having good light transmission and improved impact resistance.
