Abstract

A facile approach to the preparation of functionalized polymeric nanoparticles with UV‐crosslinkable core and bromine‐bearing shell has been developed from the polymerization‐induced self‐assembly of the block copolymers PBNBE__‐b‐PCONBI and PBNBE‐b‐PCONBI‐b‐__PONBDM. The block copolymers were characterized by means of ^1^H NMR and GPC. The polymeric nanoparticles with a fixed shell length and varied core lengths were obtained through the control of the molar ratio of monomers in the feed. The micelles were crosslinked using UV‐irradiation, and the characteristics of the polymeric nanoparticles in toluene, THF, or CHCl~3~ before and after UV irradiation were investigated by means of DLS, UV‐Vis, GPC, AFM, and TEM.
