Polymerization temperature effects on the properties of l-lactide and ε-caprolactone copolymers

Polymer Bulletin Aims and scope Submit manuscript

Summary

The large difference in reactivity of L-lactide and ε-caprolactone in ring opening polymerization with stannous octoate, leads to the formation of copolymers with blocky structures. By varying the polymerization temperature, copolymers with different average sequence lengths and molecular weights can be synthesized. It is shown that the average monomer sequence length has a large effect on the thermal and mechanical properties of these copolymers.
