Summary: This study reports on the emulsion photopolymerization of acrylate and methacrylate monomers under visible light using a disulfide photoinitiating system. The simplified boron-based system was efficient in initiating polymerization reactions and producing latexes with different particle sizes. Furthermore, the method allows for the production of random copolymer latexes with temporal control of the polymerization process.

Summary: This study describes the synthesis of new ionic liquid methacrylates and dimethacrylates and investigates the effects of different anion structures on melting behavior and photopolymerization kinetics. The results show that NTf2 and FAP are preferred over TFl and TFAc as anions in crosslinking photoinitiated polymerization due to their faster polymerization rate and higher final conversion. Interestingly, the presence of an ionic liquid methacrylate with the same anion structure as the ionic liquid dimethacrylates results in an increase in final conversion, possibly due to lower crosslink density and increased mobility during the crosslinking process.

Summary: A new type of UV-photocurable liquid varnish binder was prepared using a telomerization process and specific components including telogen and radical photoinitiator. The influence of these components on the properties of the coatings was investigated. Results showed that a varnish based on a telomers syrup containing 5 wt. parts of telogen and 0.5 wt. part of photoinitiator exhibited the highest hardness, adhesion and gloss values. Additionally, the addition of a multifunctional monomer improved various properties of the coatings, such as hardness, adhesion, scratch resistance, and resistance to water and solvents.

Summary: Structural damping plays a crucial role in the dynamic properties of mechanical structures, particularly with time-varying loads. Among various vibration reduction methods, passive vibration damping using suitable polymers with viscoelastic properties has emerged as a simple and effective approach. This study introduces a novel method for passive vibration elimination by covering low dynamic stiffness elements with polymeric pads. These polymer covers are manufactured using fused filament fabrication technology (3D printing) and joined to the structure through press connections. The study focuses on determining the damping properties of selected polymeric materials, including thermoplastic elastomers (TPE), through differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), and mechanical testing. The effectiveness of pads made from different types of polymers is evaluated through dynamic tests.

Summary: The study evaluated the in vitro penetration of ketoprofen and lidocaine hydrochloride through human skin using a transdermal vehicle. It was found that ketoprofen had higher penetration from the transdermal vehicle compared to commercial preparations, and the addition of lidocaine did not affect the permeation. The inclusion of certain excipients, such as capsicum tincture, menthol, and camphor, increased the penetration of both ketoprofen and lidocaine. This alternative method shows potential for patients with multiple diseases and polypragmasy.

Summary: A series of UV-curable urethane (meth)acrylates with different (meth)acrylic groups were synthesized and their influence on UV-curing process and self-healing properties of cured coatings was studied. The chemical structure of prepolymers was characterized by FTIR and NMR spectroscopy, and the UV-curing process was monitored in real time using FTIR and photo-DSC. The self-healing properties were characterized using various methods. The results show that the self-healing of the coatings can be controlled by reducing the effective healing temperature, making the material attractive for a variety of applications.
