 The method results in a higher molecular weight which makes the polymer more structurally sound using a process with lower toxicity than competing technologies.The market for a bio-based and biodegradable replacement for polyester is expected to grow rapidly during the next five years.The bio-based polyester, P(3-HP), has attractive mechanical properties, such as rigidity, ductility, and exceptional tensile strength in drawn films and can be created using the new lower toxicity method.
