We report the selective ring opening copolymerisation (ROCOP) of oxetane and phthalic thioanhydride by a heterobimetallic Cr(III)K catalyst precisely yielding semi-crystalline alternating poly(ester- alt -thioesters) which show improved degradability due to the thioester links in the polymer backbone.
