Abstract
In this study, we synthesized benzophenone-based main chain polybenzoxazine (BP-PBz) as a type II macroinitiator and this initiator was used to synthesize acrylate-based polybenzoxazine copolymers. BP-PBz effectively initiated the polymerization of methyl methacrylate (MMA) and poly(ethylene glycol) diacrylate (PEGDA), resulting in either polybenzoxazine-grafted-poly(MMA) or crosslinked polybenzoxazine networks. Polymerizations of the formulations were performed upon photolysis at ca. 300 nm. The obtained polymers retained their oxazine functionality and subsequent thermal curing was applied successfully at relatively lower temperatures than conventional benzoxazines. The precursors are shown to have a dual curable character that could be beneficial for deep curing purposes. The synthesized polymers were characterized using various techniques, including nuclear magnetic resonance (NMR), Fourier-transform infrared (FT-IR), ultraviolet-visible (UV–Vis) spectroscopy, and thermogravimetric analysis (TGA), along with differential scanning calorimetry (DSC).
期刊介绍:
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
