Original data of Correlative characterization of stereocomplex formation in blends of aliphatic polyester P(PCLm-b-PLLAn) block-copolymers and PDLA

Quantifying the relationship between molecular structure and macroscopic properties in phase-separating semicrystalline block copolymers is a complex challenge, yet crucial for their processing and applications in our daily life. Among others, Poly[(ε-caprolactone)-block-(L-lactide)] (P(PCL-b-PLLA) blended with Poly(D-lactide) (PDLA) hold a particular interest due to their mechanical properties. Here, we quantify the relationship between molecular structure and macroscopic properties in this class of copolymers, by combining correlative characterization techniques at different scales. P(PCL-b-PLLA) and PDLA with defined block lengths and molar masses were prepared to elucidate minimum block lengths for crystallization and stereocomplexation (SC), to characterize the size and spatial distribution of crystallites and their impact on physico-chemical properties.<br>*: to whom correspondence should be addressed.
