Synthesis and characterization of polyesters comprising 4,4'-dihydroxy
bischalcone as main chain moiety is reported here. Polyester chalcone
s were obtained by condensation of 4,4'-dihydroxy chalcones with adipi
c and terepthalic acid respectively. The polymers were characterized b
y IR and elemental analysis. The thermal and electrical behaviour were
studied by TGA, DSC, and conductivity techniques respectively. The po
lymers were found to behave like semi-conductors and were thermally st
able.
