Monodisperse highly cross-linked “living” microspheres prepared via photoinitiated RAFT dispersion polymerization

Abstract

Monodisperse highly Cross-linked “Living” microspheres were synthesized via photoinitiated RAFT dispersion polymerization of MMA using a bifunctional monomer or a trifunctional monomer as the cross-linker.

Copper and iron complexes as visible‐light‐sensitive photoinitiators of polymerization

“…To expand these approaches to particular applications where the reactions need to be conducted at low temperatures (e.g., polymerization of monomers with low ceiling temperatures or biochemical applications), a photoinduced radical polymerization process becomes an excellent candidate . Many works have recently been reported in this field such as photo‐ATRP 69, or photo‐RAFT . The CuCs‐based PISs proposed so far are capable of initiating photo‐ATRP.…”

One-pot synthesis of micron-sized polybetaine particles; innovative use of supercritical carbon dioxide

“…25 The addition of a cross-linker can have a significant influence on the particle morphology in heterogeneous polymerisations, as the initial particle nucleation and growth, and overall colloidal stability are very sensitive to cross-linker addition. 26 29 controlled using RAFT polymerisation, 30 and using acetone as a co-solvent. 31 Interestingly, in pure scCO 2 the particles were highly agglomerated, but with increasing acetone concentration the particles became more discrete and also more uniform in size (around 2 µm).…”

Facile Preparation of Monodisperse Poly(2‐hydroxyethyl acrylate)‐Grafted Poly(methyl methacrylate) Microspheres via Photoinitiated RAFT Dispersion Polymerization

“…Fabrication of polymer‐grafted polymeric microspheres is usually achieved by surface‐initiated polymerization of polymer particles with reactive groups (e.g., initiator and chain transfer agent) on the surface. By using this approach, various polymeric microspheres with high density of grafted polymers on the surface have been prepared . However, this two‐step methodology is relatively complex and time‐consuming, which is difficult to implement on a large scale.…”
