✦ Synopsis

The propargyl alcohol has been polymerized in the presence of [Pd(C_~C-CH2OH)2(PPh3)2] and [Rh(cod)C1]2 catalysts and polymers (POHP) with different structures are obtained. By comparison with polyphenylacetylene, a cis-transoidal configuration of POHP prepared with the Rh(I) catalyst may be suggested. The characterization of POHP has been performed by means of i.r., n.m.r., SEM and g.p.c. measurements. Doping with I2, the associated isomerization process and the resistance variations are also discussed.
