Polyacrylonitrile colloids were obtained by codeposition at 77 K of the monomer with several metals such as: Au, Pd, Ge, Ga, In, Sn, Sb and Bi. The colloids after warm up were polymerized with different amounts of initiators (AIBN) at 283 K and a wide range of viscosimetric molecular weights (M?105) were obtained depending upon the metal involved. The colloid metal dispersions concentrations are reported. The metal composition is ranging between 0.4–7.0 %. The thermal stability and metal microanalysis is also described. The polymers are stable up to 573 K. |
