K. Naka et al., SYNTHESIS OF A STAR-SHAPED POLYMER HAVING TRIS(BETA-DIKETONATO)CHROMIUM(III) AT THE CENTER CORE, Polymer bulletin, 41(3), 1998, pp. 263-266
The metal-centered star-shaped polymer was prepared by coordination of
p-(1,3-butanedionyl)-terminated poly(oxyethylene) with Cr(III) ion. T
he structure was confirmed by GPC analysis and IR spectra. The resulti
ng polymer complex was well-soluble in various organic solvents and wa
ter.
