Easy-dispersible poly(glycidyl phenyl ether)-functionalized graphene sheets obtained by reaction of "living'' anionic polymer chains

Barroso-Bujans, Fabienne; Boucher, Virginie M.; Pomposo, José A.; Buruaga, Lorea; Alegría, Ángel; Colmenero, Juan (Royal Society of Chemistry, 2012)

Excellent dispersion of functionalized graphene (FG) sheets in polystyrene was achieved relying on the reaction of “living” poly(glycidyl phenyl ether) chains onto graphene sheets. The physical aging of polystyrene was ...
On the Apparent SEC Molecular Weight and Polydispersity Reduction upon Intramolecular Collapse of Polydisperse Chains to Unimolecular Nanoparticles

Pomposo, José A.; Buruaga, Lorea; Perez Baena, Irma; Alegría, Ángel; Colmenero, Juan (ACS Publications, 2011)

When unimolecular particles of molecular weight M are formed by intramolecular cross-linking of individual polymer chains, a significant reduction in hydrodynamic radius and, hence, apparent molecular weight (Mapp) is found ...
