Abstract Poly(β‐hydroxybutyrate) (PHB) is a bacteria storage biodegradable polyester that is considered to be a natural substitute for synthetic thermoplastics in many applications. However, brittleness hampers its utility. This study shows that oriented elastic fibers of PHB with favorable mechanical properties (360‐MPa tensile strength and 5.6‐GPa Young's modulus) can be produced by the spinning and drawing of a concentrated PHB gel using a three‐stage fiber processing technique. © 2001 John Wiley & Sons, Inc.
