Synthesis and Characterization of Acrylate‐Based Block and Block‐Graft Copolymers Using Polyester‐Based Macro‐RAFT Agents Through Two‐Step Polymerization and Assessment of One‐Pot Epoxy Group Ring‐Opening Modification

Polymer Engineering &Science, EarlyView.
Schematic diagram of RAFT polymerization of acrylate monomers. ABSTRACT This study reports the synthesis of a macro‐RAFT agent based on poly(ɛ‐caprolactone) (PCL) via ring‐opening polymerization (ROP), which was subsequently used to prepare acrylate‐based block and block‐graft copolymers through RAFT polymerization.

Mechanochemical atom transfer radical polymerization unlocks functional methacrylate lifecycles of controlled synthesis, force-activated degradation, and depolymerization

Nature Communications
Mechanochemical polymerization offers a solvent-free alternative to conventional solution-based methods. However, achieving controlled radical polymerization poses challenges due to the competing interplay between chain propagation and polymer ...

Tailored for Binding: Alanine‐Modified Poly(1‐Naphthylamine) Targets Serum Albumins

Polymer Engineering &Science, EarlyView.
Alanine modified poly(1‐naphthylamine). ABSTRACT This study presents a new approach for modifying the structural and functional properties of poly(1‐naphthylamine) (PNA) by incorporating the amino acid alanine (Ala) in different molar proportions (80/20, 50/50, and 20/80 for PNA/Ala) through an ultrasound‐assisted polymerization process.

Synthesis of Poly(Itaconate)s With High Monomer Conversion Applying Emulsion Polymerization

Journal of Polymer Science, Volume 63, Issue 6, Page 1284-1296, 15 March 2025.
Itaconic acid and its derivatives are a promising and bio‐based substitute for oil‐based polymers such as acrylates. In this study, the optimization of polymerization of itaconic acid esters is described by applying emulsion polymerization leading to high reaction conversions and low residual monomer contents. ABSTRACT Itaconic acid and its derivatives

Preparation and Characterization of Hyperbranched Polystyrene Nanocomposite Synthesized by Living Radical Polymerization and Solution Intercalation Method [PDF]

علوم و تکنولوژی پلیمر, 2013
A copolymer of styrene and methyl styrene was synthesized by nitroxide - mediated “living” free radical polymerization )NMP). N-Bromosuccinimide was used as a brominating agent to obtain a copolymer with bromine as its end group.
