Photo‐triggering curing coatings have advantages of improving production efficiency, reducing pollution emissions, and contributing to green environmental protection. However, making the trade‐off between appropriate viscosity and UV‐curing properties in a high‐performing polymer system remains a formidable challenge. In this paper, firstly, a series of acrylate copolymer oligomers (named as PAAR) were synthesized using methyl methacrylate (MMA), butyl acrylate (BA), and glycidyl methacrylate (GMA), then methacrylic acid (MAA) was grafted utilizing the reaction between carboxyl group in MAA with epoxy group in oligomer to introduce double bonds. By adjusting the oligomer molecular weight to control the viscosity and changing the GMA ratio to obtain suitable double bonds content. As a result, the number molecular weight (Mn) of the thus‐obtained PAAR oligomers were less than 3000 Da, and the polymer dispersity indexes (PDI) were lower than 1.8. Photo‐polymerization kinetics revealed that the coating prepared using the oligomers could be fully cross‐linked by UV light triggering within 60 s, achieving a high transparency of 90% along with favorable thermal and mechanical properties. Furthermore, it was confirmed that the water resistance on the surface of the cured films and hydrophobicity were more influenced by the presence of hydroxyl groups. [ABSTRACT FROM AUTHOR]

In this paper, novel embolic microspheres with efficient drug delivery and slow drug release properties were developed, which have potential applications in transarterial chemoembolization (TACE). The microspheres were prepared by suspension polymerization using vinyl acetate, 10‐Undecen‐1‐ol (UO), multi‐walled carbon nanotubes, and crosslinking agent (1,4‐butanediol divinyl ether). In the process, porous titanium tubes are used to control the particle size of the microspheres. In addition, the introduction of long‐chain (UO) makes the microsphere good swelling property in acetone. Multi‐walled carbon nanotubes modified by hexadecyltrimethoxysilane (HDTMS) are helpful for increasing both spherical morphology stabilization and swelling properties in acetone as well (C‐PVA‐2UO/CNT). Target drug was dissolved in acetone and the mcirospheres were dispersed in acetone to realize drug load. In vitro biocompatibility analysis showed that C‐PVA‐2UO/CNT is non‐cytotoxic and hemocompatible. The sustained drug release properties of C‐PVA‐2UO/CNT were confirmed by drug indomethacin (IMC) loading and release experiments. These findings suggest that the newly developed C‐PVA‐2UO/CNT has great potential to be used as a drug‐loaded embolization agent. [ABSTRACT FROM AUTHOR]
