ABSTRACT:
The tensile modulus of fibers made from liquid crystalline polymers comprising 6-oxy-2-naphthoate and 4-oxybenzoate monomer units that have been heat treated can be increased by applying and then releasing a stress at room temperature in the range of about 25% to about 90% of the tensile strength of the heat treated fiber to yield a "pre-stressed" fiber.
