Abstract

DDT (I) was polycondensed with 2,2‐bis(4‐hydroxy phenyl)‐ propane (bisphenol‐A) to form polyether. The following monomers were synthesised from DDT: 2,2‐bis(4‐chloro‐phenyl)1, 1‐dichloroethylene(II), 2,2‐bis(3‐nitro‐4‐chlorophenyl)ethane (III) and 2,2‐bis (3‐nitro‐4‐chloro‐phenylethylene (IV) and polycondensed with bisphenol‐A. They were also copolymerised with bis(4‐chlorophenyl)sulphone and bisphenol‐A in several molar ratios. The polymers and copolymers were characterised by various techniques. The results obtained show that the DDT has a low reactivity, but nitration and dehydrochlorin‐ation increases its reactivity to a significant extent.

## Abstract The thermal decomposition of pure D.D.T. at various temperatures has been examined by direct measurement of the hydrogen chloride evolved in the reaction. The evolution of gas is only very slight at the melting point of the compound, but it is rapid in the neighbourhood of 200°. Express
