Abstract
The copolymerizations of (4S, 5S)-2-p-styryl-4, 5-bis [(diphenylphosphino) methyl]-1, 3- dioxolane [(S, S)-5] with a cross-linking monomer, ethylene 1, 2-dimethacrylate (7), and methacrylatea bearing both a primary alcohol function and a chiral secondary alcohol function,(2S)-,(2RS)-, or (2R)-2, 3-dihydroxypropyl methacrylate [(S)-2,(RS)-2, and (R)-2, respectively], gave polymers (68-2, respectively) onto which rhodium was exchanged via ...
