Abstract
A process of imbibition drawing is improved by a pretreatment that preferably involves straining an undrawn filament bundle, or other elongated shaped undrawn or partially drawn synthetic polymeric article, while wetted with a cracking agent, before incorporating a desired additive by imbibition drawing, thereby increasing the imbibition capacity of the article, and improved articles incorporating such additives. Alternatively or in addition the pretreatment involves polarizing irradiation, before imbibition drawing.
