Exploitation of dinuclear salan aluminum complexes for versatile copolymerization of ε-caprolactone and L-lactide.
By combining the influence of excess alcohol, temperature and monomer-to-initiator ratios in the feed, dinuclear salan aluminum complexes L(R)Al(2)Me(4) exhibited a high degree of control towards the copolymerization of L-LA and ε-CL, producing blocky, gradient, tapered and random copolymers.
