Abstract
The synthesis, characterization and application of the polymers with functional pendant groups have always been hot topics in the polymer field. A kind of functional polybutadiene (HTPB) derivative containing anthryl and azide groups was synthesized by anthracenic acid and HTPB in the presence of N-bromosuccinimide (NBS) and sodium azide via an electrophilic reaction. Furthermore, the HTPB derivative N3-HTPB-AN as a macromolecular main chain was reacted with alkynyl-terminated polytetrahydrofuran (Alk-PTHF) and maleimide-terminated polyethylene glycol (Mal-PEG) through "azide-alkyne" and "Diels-Alder" click reaction to obtain a bottle-brush polymer with the HTPB as the main chain and polytetrahydrofuran and polyethylene glycol as the side chains by one-pot. The bottle-brush polymer could self-assemble into uniform nanommicelles in aqueous solution. Meanwhile, the photoregulated fluorescence resonance energy transfer (FRET) exhibited by the interaction of the micelles assembled by the bottle-brush polymer in water with the dye was studied.
