Polyesters containing chalcone moiety were synthesised from 1, 3-bis (4-hydroxy-3-methoxyphenyl) propenone (BHMPP) and 1- (3, 5-dihydroxyphenyl)-3-(4-methoxyphenyl) propenone (DHPMPP) with suberoyl and sebacoyl chlorides by an interfacial polycondensation technique. Fundamental studies on the two phase polycondensation using phase transfer catalyst (tetra n-butylammonium bromide) was done. The synthesised polymers were characterised by solubility measurement, intrinsic viscosity, IR, 1H and 13C NMR studies.
