Abstract
A method for producing a lactide block copolymer, to a lactide block copolymer and to an article including the lactide block copolymer. In particular, the instant invention relates to an improved lactide block copolymer which may be obtained by providing a polymer of a first lactide monomer including a residual amount of the first monomer, adding and polymerizing a first amount of a second monomer of opposite chirality and subsequently adding and polymerizing a second amount of the second monomer. The resulting lactide block copolymer generally has a high melting point (e.g. from 190 to 250° C.).
