Abstract
Dendritic 2- and 4-arm PMMA-based star polymers with furan-protected maleimide at their focal point, (PMMA)2n-MI and (PMMA)4n-MI were efficiently clicked with the peripheral anthracene functionalized multiarm star polymer, (α-anthryl functionalized-polystyrene)m-poly(divinyl benzene) ((α-anthryl-PS)m-polyDVB) through the Diels–Alder reaction resulting in corresponding multiarm star block copolymers: (PMMA)2n-(PS)m-polyDVB and (PMMA)4n-(PS)m-polyDVB, respectively. Molecular weights (Mw,TDGPC), hydrodynamic radius (Rh), and intrinsic viscosity (η) of the multiarm star polymers were determined using three-detection GPC (TD-GPC). The high efficiency of this methodology to obtain such sterically demanding macromolecular constructs was deduced using 1H-NMR and UV–vis spectroscopy. © 2010 Wiley Periodicals, Inc.
