The polyaniline poly(ethylene terephthalate) composite 1. Peculiarities ofthe matrix aniline redox polymerization

The formation of the conducting polyaniline/poly(ethylene terephthalate) co mposite by the chemical redox polymerization of An in the matrix has been i nvestigated. The process runs in the chlorine (bromine) containing water me dium under the action of the products of the halogen hydrolysis. The possib ility and peculiarities of the process strongly depend on a matrix nature. In particular, it could not be realised in polypyromellitimide and poly(vin ylidenefluoride) matrixes but run in poly(ethylene terephthalate), bispheno l-A polycarbonate and polyvinylchloride ones. It is supposed that high spec ificity of this process in terms of a choice of the matrix and oxidant is a consequence of formation of the transition state including An molecule, th e elementary unit of poly(ethylene terephthalate) and HOCl molecule, antece dent to the starting reaction (the An oxidation).
