An account is presented of recent work on specially synthesised diblock, triblock and cyclic block copolymers of ethylene oxide and 1,2-butylene oxide. Simultaneous small-angle X-ray scattering and differential scanning calorimetry have been used to investigate the effects of block architecture on the stabilities and structures of microphase-separated melts. Stable lamellar, hexagonal, body-centred cubic and gyroid phases were detected. Phase diagrams are compared, one with another and with those predicted by the exact self-consistent mean-field theory, and centre-block stretching in lamellar phases is confirmed.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
