Abstract

Styrene-methyl methacrylate colloids were obtained by codeposition at-196°C of the monomer with metals, such as: Au, Pd, Cu, Ga, In, Sn and Bi. The colloids were polymerized with various amounts of initiator (AIBN) at 60°C and a wide range of viscosity average molecular weights (Mv; 2.0x104−1.9x105) were obtained depending upon the metal used. The metal colloid concentrations are reported. The thermal stability and metal composition are also described. The copolymers of Au, Ge, Pd and Sn are stable even at 300°C. The metal content is 0.9 to 11% with an exception of 22% for Au.
