Ultrathin fibers could be prepared by nozzle-less electrospinning from solutions of biodegradable polyhydroxybutyrate (PHB) polyesters and its mixture with polycaprolactone in CHCl3. The formation region of the continuous network of linkages that was required for stable electrospinning of the fibers was established by studying the PHB solution viscosity as a function of concentration. It was found that microscopic amounts of HCl could regulate the viscosity of solutions of high-molecular-weight PHB.
