“…Moreover, a typical kinetic behavior for radical polymerization confined in a preformed microenvironment was observed, which is in agreement with a radical polymerization mechanism involving complexes between the polymer and MMA on copper ion. 96 A redox initiation approach was followed elsewhere to efficiently graft BA 97 and MMA 98 Moreover, another novel synthetic method to create casein/ polymer amphiphilic nanoparticles and overcome such oxidative problems of persulfate initiators was developed in the later works of Li and co-workers 79,99 It consists of an EF-EP in which an organic hydroperoxide (ROOH) initiator, such as tert-butyl hydroperoxide (TBHP), reacts with the amino groups present in casein, generating radicals in their N atoms. 79 The radicals formed onto casein amine groups initiate the graft copolymerization of MMA, and as these radicals become water insoluble they assemble into polymer NPs precursors.…”

The pursuit of sustainable and environmentally friendly materials has been powered by environmental concerns and the decline in oil reserves. Among the different routes toward this end, the replacement of oil-based materials by renewable materials stands out. In this way, protein based materials have gained interest. This review article summarizes the progress achieved in the synthesis of hybrid protein/synthetic polymer nanoparticles which have the potential to be used in industrial applications. Although technical achievements and efficacy proofs concerning the increased compatibility of polymer/protein are already available, practical implementation in industry still represents an additional challenge and should be the focus of interest in future research. The available literature supports the potential of hybrid protein/polymer nanoparticles in the production of ecofriendly alternatives for large scale applications as coatings, paints, adhesives and films.

Spontaneous polymerization of amphiphilic vinyl monomers, 1. Spontaneous polymerization of sodium dodecyl 2‐hydroxy‐3‐methacryloypropyl phosphate

Sodium dodecyl2-hydroxy-3-methacryloyloxypropyl phosphate as an amphiphilic vinyl monomer was found to polymerize spontaneously without initiator in water. The polymerization takes place at a monomer concentration higher than the critical micelle concentration via a free-radical mechanism, and complete conversion is achieved even at a very low initial monomer concentration (3 mmol/L) and arather low temperature (35 "C). In benzene, capable of forming inverse micelles, the polymerization also occurs spontaneously. In methanol, which gives an isotropic solution, the spontaneous polymerization proceeds only at high concentration (near 300 mmol/L). The 'H spin-spin relaxation time (T2r) of the monomer changes discontinuously in a range of monomer concentration from 250 to 300 mmol/L in CD,OD, suggesting that some kind of monomer mutual interaction takes place in methanol too. Thus, it can be concluded that the micellar aggregation of monomer molecules triggers the polymerization.
