Abstract:
The present invention provides a multi-block copolymer comprising at least blocks A-B-A or B-A-B, wherein block A comprises a polyester formed by polymerisation of a lactone and/or a lactide; and block B comprises a copolyester formed by polymerisation of an epoxide and an anhydride, or a polycarbonate formed by polymerisation of an epoxide and carbon dioxide, and methods of production thereof.
