Abstract
This study reports the synthesis of acrylate-based polymers with diverse topologies, including cyclic and 8-shaped structures, using a combination of atom transfer radical polymerization (ATRP) and click coupling reactions. The linear and tetra-arm poly(tert-butyl acrylate) (PtBA) polymers with similar molar masses are synthesized via the activators regenerated by electron transfer atom transfer radical polymerization. These polymers are further transformed into cyclic and 8-shaped topologies, respectively, through a click reaction. All topologies possessed similar molar mass are confirmed using 1H NMR, FT-IR, SEC, and MALDI-TOF mass spectrometry. The influence of macromolecular topology on intrinsic viscosity and glass transition temperature (Tg) is systematically investigated. The findings show that within the PtBA topology series, Tg increases with structural compactness, with cyclic polymers exhibiting higher Tg than their precursors. Additionally, intrinsic viscosity decreases as compactness increases across the various topological macromolecules. These observations highlight the potential of topology as a tool for fine-tuning polymer properties, facilitating the development of advanced materials with specific behaviors in solution and bulk properties.

Abstract
Hyperbranched polymethacrylates were synthesized by green-light-induced atom transfer radical polymerization (ATRP) under biologically relevant conditions in the open air. Sodium 2-bromoacrylate (SBA) was prepared in situ from commercially available 2-bromoacrylic acid and used as a water-soluble inibramer to induce branching during the copolymerization of methacrylate monomers. As a result, well-defined branched polymethacrylates were obtained in less than 30 min with predetermined molecular weights (36 000<Mn <170 000), tunable degree of branching, and low dispersity values (1.14≤Đ≤1.33). Moreover, the use of SBA inibramer enabled the synthesis of bioconjugates with a well-controlled branched architecture.
