✦ Synopsis

Addition of bulky Cso moiety, a powerful electron acceptor (EA = 2.6-2.8 eV), to the poly(pbromostyrene)(PBS) by a novel organometallic reaction considerably changes the chemical and physical properties of this polymer. The product obtained is a "charm-bracelet'' noncrosslinked brownish yellow polymer which is easily soluble in many common organic solvents, and has a single glass transition temperature [134.OoC vs. 83.2"C for poly(pbromostyrene)], this being congruent with its chemical structure. Covalent attachment of Cso to the brominated polystyrene backbone is confirmed by a variety of techniques such as UV-VIS, FT-IR, TGA, DSC, SEM, ESR, GPC, and 13C-NMR. The results show that both the stereo-electronic effect and the steric hindrance of Cs0 have an important influence on the structure and physical properties of polymer. 0 1996
