Abstract: | Block copolymers (BCPs) in the bulk state are known to self‐assemble into different morphologies depending on their polymer segment ratio. For polymers with amorphous and crystalline BCP segments, the crystallization process can be influenced significantly by the corresponding bulk morphology. Herein, the synthesis of the amorphous‐crystalline BCP poly(dimethyl silacyclobutane)‐block‐poly(2vinyl pyridine), (PDMSB‐b‐P2VP), by living anionic polymerization is reported. Polymers with overall molar masses ranging from 17 400 g to 592 200 g mol⁻¹ and PDMSB contents of 4.8–83.9 vol% are synthesized and characterized by size‐exclusion chromatography and NMR spectroscopy. The bulk morphology of the obtained polymers is investigated by means of transmission electron microscopy and small angle X‐ray scattering, revealing a plethora of self‐assembled structures, providing confined and nonconfined conditions. Subsequently, the influence of the previously determined morphologies and their resulting confinement on the crystallinity and crystallization behavior of PDMSB is analyzed via differential scanning calorimetry and powder X‐ray diffraction. Here, fractionated crystallization and supercooling effects are observable as well as different diffraction patterns of the PDMSB crystallites for confined and nonconfined domains. |
