Biodegradable Polymers are of special interest for various applications. However, as an environmental friendly alternative for commodity polymers for mass products such as packaging materials, a more cost-efficient synthesis compared to biotechnological path-ways is required. In this work different catalytic routes towards poly(3-hydroxybutyrate)from commercially available feedstocks have been evaluated. For the most promising pathway, the ring-opening of β-butyrolactone, a promising class of chromium-salphene-species has been evaluated. Based upon these findings, two new and highly active zinc catalysts have been developed, which generate high molecular weight polymers at moderate reaction conditions.
