G. Cardenas et E. Salgado, METAL POLYMERS - SYNTHESIS AND MOLECULAR-WEIGHTS OF METAL POLY(4-METHYLSTYRENE)S WITH ALBN .8., Polymer bulletin, 33(6), 1994, pp. 629-634
4-Methylstyrene colloids were obtained by codeposition at 77 K of the
monomer with several metals such as Au, Ag, Cu, Pd, Zn, Ga, in, Ge, Sn
, Sb, Bi. The colloids were polymerized with different amounts of init
iator (AIBN) at 65 degrees C for 9 h and a wide range of viscosity ave
rage molecular weights (($) over bar Mv, 10(3)-10(5)) were obtained de
pending upon the metal used. The metal colloid concentration and stabi
lity are reported. The most stable colloids were Au, Pd and Ga being i
n solution for several months at room temperature. The thermal stabili
ty and metal composition are also described. The polymers are stable e
ven at 385 degrees C, being Pd with Ge-poly(4-methylstyrene) the most
stable. The metal content is ranging between 0.14 and 0.55 (w/w) with
Pd and Sn, respectively.
