Abstract

A poly(vinylidene chloride-co-Me acrylate) hybrid latex comprising CeO2 nanoparticles was successfully prepd. by emulsion polymn. employing a water-sol. phosphonated macro-RAFT agent. A poly(vinylbenzylphosphonic diacid-co-styrene) statistical copolymer was first synthesized, using dibenzyl trithiocarbonate as a controlling agent, and adsorbed on ceria nanoparticles. UV-visible and 31P NMR spectroscopy proved to be efficient and complementary techniques to assess the extent of interactions between the copolymer and ceria nanoparticles, leading to a better understanding of the adsorption of phosphonated copolymer chains on inorg. particles. Then, these functionalized-CeO2 nanoparticles were used to mediate the emulsion copolymn. of vinylidene chloride and Me acrylate in the presence of a very low amt. of emulsifier. Cryo-transmission electron microscopy (cryo-TEM) confirmed the hybrid structure of the latex and the absence of either free ceria nanoparticles or free PVDC latex particles.
