      abstract     = {In phase-separating multiblock copolymers it is a challenge
                      to quantify the relationship between molecular structure and
                      functional properties, yet this quantification is crucial
                      for processing and applications. Here, we describe the
                      molecular structure and phase behavior-properties
                      relationships for a modular system of
                      poly[(ε-caprolactone)-b-poly(L-lactide)] multiblock
                      copolymers with well-defined long/short block lengths and
                      their blends with poly(D-lactide) (PDLA) of varying lengths.
                      The formation of crystallite types and sizes as well as
                      absolute and relative crystallinities of PCL, PLA
                      homocrystallites (HC), and PLA stereocrystallites (SC) were
                      studied by DSC and WAXS, and visualized by TEM, POM, and
                      AFM. We reveal that SC formation occurs in blends containing
                      a ratio between 1 : 1 and 1 : 4 ratio of PDLA and
                      PLLA. In systems with much longer PCL than PLLA sequence
                      length (113 : 18), SC formation is inhibited. Blend
                      crystallinity was highest for a medium PDLA length. SC
                      formation is preferred over HC formation, and SCs act as
                      nucleation points for PCL crystallization. In our work the
                      segment length had a trend to correlate with crystallite
                      sizes. Tensile strength (from 0.5 to 8 MPa) and elongation
                      at break (from $10\%$ to $>750\%$ at room temperature) could
                      be increased simultaneously by allowing SC formation, which
                      in the studied blends correlated with low overall
                      crystallinity. Our study shows strategic polymer synthesis
                      and blending for the precise control of stereocomplex
                      formation and fine-tuning in high-performance PLA-based
                      materials. These findings support the knowledge-based choice
                      of blend composition and segment length to tailor versatile
                      materials with tunable mechanical and thermal properties.},
