“…The ATRP process can be efficiently applied in both homogenous and heterogenous media. [23][24][25][26] Surface-initiated ATRP (SI-ATRP) offers a versatile solution to control the surface characteristic dictating the interaction and response of the material to the different fluids with which it may come into contact. [27,28] The first step toward ensuring an efficient process is the grafting of initiator molecules onto the surface that requires functionalization.…”

The first aim of this study is to develop a photo‐ATRP process using methyl methacrylate (MMA) by employing a novel perylenediimide derivative (PDI) as photoinitiator. The analysis of the MMA photopolymerization process kinetics is performed in solution and in bulk, demonstrating control over the reaction progress even if the polymerizations display a slow initiation step. The photo‐ATRP process for MMA in suspension is also developed and the obtained PMMA particles are further used to reinitiate the ATRP polymerization of thermoresponsive polymers (different molecular weights poly(ethylene glycol) methyl ether methacrylate and poly(N‐isopropylacrylamide)) (PNIPAM) in solution and surface‐initiated processes. The synthesized polymers by surface‐initiated process display a bimodal molecular weight distribution with a clear modification of the signal areas ratio depending on the grafted monomer and on the reaction conditions. The grafting process can take place on the surface of the polymer particles (Mn2), or it can also involve polymer chains located further at the interior of the polymer particles (Mn1). The lower critical solution temperature (LCST) transition is demonstrated for the PNIPAM functionalized polymer particles.

“…The industrial polymerizations are mainly carried out in a normal oil-in-water (O/W) system or an inverse water-in-oil (W/O) system [52,53]. Various polymer structures, including block [27,54], star [55][56][57] and brush [58][59][60], were synthesized in water-dispersed media (microemulsion [61][62][63], miniemulsion [64][65][66], and emulsion [67][68][69][70]). Emulsion and miniemulsion methods belong to a heterogeneous environment ATRP techniques in dispersed media are especially beneficial for obtaining multifunctional polymers with narrow molecular weight distribution (MWD, Mw/Mn, Đ) and a predetermined molecular weight (MW), as segregation and compartmentalization decrease the rate of termination processes [47][48][49].…”

In the last decade, unceasing interest in atom transfer radical polymerization (ATRP) has been noted, especially in aqueous dispersion systems. Emulsion or miniemulsion is a preferred environment for industrial polymerization due to easier heat dissipation and lower production costs associated with the use of water as a dispersant. The main purpose of this review is to summarize ATRP methods used in emulsion media with different variants of initiating systems. A comparison of a dual over single catalytic approache by interfacial and ion pair catalysis is presented. In addition, future development directions for these methods are suggested for better use in biomedical and electronics industries.
