Some new polyamidoethers have been synthesized by condensation reaction of N,N '‐dichloroacetyl‐1,4‐phenylene‐diamine with bisphenols (4,4'‐isopropylidenediphenol, 4,4'‐dihydroxydiphenyl sulfone, 4,4'‐dihydroxydiphenyl sulfide, and 4,4'‐dihydroxybiphenyl) in N ‐methylpyrrolidone medium using DB‐24‐Crown‐8 as a phase‐transfer catalyst. The structure of these polymers has been characterized by infrared (i.r.) and 1 H nuclear magnetic resonance (NMR) spectroscopy. Kinetic method of thermal decomposition of these polymers and their 2% mixture with polyvinylchloride (PVC) has been studied.
