Résumé
Polymerization-induced self-assembly (PISA) and in situ crosslinking of the formed nanoparticles are successfully realized by activators regenerated by electron-transfer atom transfer radical polymerization (ARGET ATRP) of glycidyl methacrylate (GMA) or a mixture of GMA/benzyl methacrylate (BnMA) monomers in ethanol. Poly(oligo(ethylene oxide) methyl ether methacrylate) was employed as macroinitiator/stabilizer, and a cupric bromide/tris(pyridin-2-ylmethyl)amine complex as catalyst. Tin (2-ethylhexanoate) was used as reducing agent for ARGET ATRP, and simultaneously acted as a catalyst for ring-opening polymerization of oxirane ring in GMA. The kinetics shows that the double bond in GMA was completely polymerized in 4.0 h, while only a 33% conversion of oxirane ring in GMA was reached at 117.0 h. Such a large difference would guarantee a smooth PISA and a subsequent in situ crosslinking of formed nanoparticles. The transmission electron microscopy and dynamic light scattering show spherical nanoparticles formed. With a feed molar ratio [BnMA]
