Undrawn filaments of poly-trans-quinitol adipate and sebacate were obtained by melt spinning of these polymers.
By drawing filaments at 95° in a water bath, maximum drawing ratio reached to 10 times for sebacate and 4 times for adipate. Specific gravities of filaments were also increased by hot drawing.
Stress-strain curves of these drawn and undrawn filaments were obtained by Instron tensile tester. Tensile strength and elongation of maximum drawn filaments were 3.9g/d and 12% for sebacate, and 2.8g/d and 9% for adipate. The decrease of tensile strength of these hot drawn filaments by exposure to ultraviolet light was almost of the same grade against these of the existing practical fibers.
It has been shown through X-ray diffraction patterns of drawn and undrawn filaments that there was good crystallinity, and calculated values for identity periods were 13.5Å for adipate and 18.5Å for sebacate respectively.
The anther discussed the possible configuration of molecular chain of trans-quinitol polyester through these values.
