Abstract
Three novel polyacetylenes :
Polyacetylene PAs, 1-ether- benzoic acid-2- ene - propylene (A) .
Polydiacetylene (PDAs), hexa -1,6 diphthalmide - 2- ene – 4 –yne ( B ) ,and
Polyacetylene PAs , 1- phenyl - 3- butyne -1 -ol ( C) .
were prepared through polymerization of three Acetylinic monomers. They were prepared byby
reaction of propargyl bromide, unsaturated alkyl halide RX and With, other various reagents))
Polymerization was carried out by using selective catalyst such as CuCl, PdCl2 complexed of
transition metals with dry and pure oxygen . polymers were extracted , purified and identified by FTIR,
HNMR Spectroscopy and melting points . Electrical conductivity of polymers was studied after
doping with iodine (I2) to increase their conductivities . Composite plastic was prepared from
polymethyl metha acrylate PMMA as the matrix with Polyacetylene as the filler by cast molding the
solution of plastic and polyacetylene was prepared by mixing with THF as solvent. The conductivities
of the composite seem to be close to semiconductors and the results are in agreement with the literature
