| 1. Polymer nanoparticles, which have a controlled architecture selected from the group consisting of nano-necklace and nano-cylinder;
and which comprise a core polymerized from multiple-vinyl-substituted aromatic hydrocarbons, a shell polymerized from alkyl-substituted
styrene monomer, and a styrene monomer layer between the core and the shell;
wherein the styrene monomer and alkyl-substituted styrene monomer form diblock copolymers.
