Copolymer formed of constitutional repeating units that are constitutionally identical but configurationally different.
Note: In transesterification and hydrolytic degradation reactions of lactic-acid stereocopolymers, the intrachain ester bonds in \(m\), \(r\), and heterochiral short sequences exhibit different reactivity.
