Synthesis, characterization, and kinetic study on the thermal decomposition of polyamidoethers

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 ¹H nuclear magnetic resonance (NMR) spectroscopy. Kinetic method of thermal decomposition of these polymers and their 2% mixture with polyvinylchloride (PVC) has been studied.
