要旨

The kinetics of bulk photo-polymerisation of multifunctional monomers, leading to highly cross-linked polymers, has been investigated by in situ real-time Raman spectroscopy. The decrease with time of the monomer content is described by a modified Gompertzian function originally developed for population dynamics. This function is flexible enough to take into account inhibitor effect, gel effect and glass effect which are characteristic for curing of technical polymer coatings. Layers of commercial acrylic resins with a thickness of 50 μm, with commercial initiators, are taken as model systems for the UV-curing. The proof-of-concept is presented that the combination of Raman hardware and Gompertzian software enables systematic laboratory tests of curable systems.

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.
