Abstract: Abstract In this work we report the effects of single stage zone drawing on the properties of NEW‐TPI thermoplastic polyimide homopolymer, and its blends with Amoco's Xydar liquid crystalline polymer. Zone drawing was performed first on homopolymer NEW‐TPI films to determine the effect of load weight, heater speed, and drawing temperature on the attainable draw ratio. Degree of crystallinity and chain orientation increase as the draw ratio increases for NEW‐TPI. Blends of NEW‐TPI/Xydar compositions 90/10 and …
