Ethyl etoxy zinc (II) has been prepared and emerged as very effective initiators for ring-opening polymerization of 1,3-trimethylene carbonate (TMC) and its copolymerization with ε-caprolactone (CL) to produce high molar mass polymers. The copolymerization of TMC and CL was performed in bulk at 120°C. The obtained copolymers were characterized by multiblock microstructure. The highest reactivity rate was demonstrated by trimethylene carbonate in comparison with ε-caprolactone monomer. The thermal and mechanical properties of the copolymers were strongly dependent on the monomer composition. Preliminary tests of monomers copolymerization using reactive extrusion yielded positive result.
