Abstract
New PPV derivatives containing cross-linkable acetylene groups, poly(2 -methoxy-5-propagyloxy-1,4-phenylevinylene) (PMPPV) and its PPV copoly mers were synthesized through the soluble precursor polymers. PMPPV fi lm was higly cross-linked and lost its properties of a conjugated poly mer at over 200 degrees C. The electrical conductivities of PMPPV film s were measured by four probe method after FeCl3 doping. The undrawn a nd 10 times drawn PMPPV films showed thier electrical conductivities o f 1.5 x 10(-1) and 92 S/cm, respectively. Conjugation length of poly(P V-co-MPPV) was controlled by changing the PMPPV monomer feed ratio.
