A polycaprolactone copolymer and a polylactic acid precursor, both suitable for use as a polymer precursor in a resin composition. The polycaprolactone copolymer comprises a backbone chain, the backbone chain comprising one or more diol units, e.g. butanediol, one or more units of a dicarboxylic acid or a dicarboxylate or a derivative thereof (e.g. one or more fumarate units), and further comprising one or more acrylate units. The polylactic acid copolymer comprises a backbone chain, the backbone chain comprising one or more butanediol units and further comprising one or more acrylate units adjoined to a polylactic acid residue. |
