Description / Table of Contents:
Die Kondensation von Triphenylamin mit Bissäurechloriden gab mit Zinkchlorid bei 25°C oder mit Aluminiumchlorid bei 5°C lösliche, lineare Polymere. Phosgen, Thionylchlorid und Dichlormethan kondensierten mit Triphenylamin ebenfalls zu Polymeren. Die Substitution in p-Stellung erfolgte nur an zwei Phenylresten bei Verwendung von ZnCl2. Die Substitution am dritten Phenylrest in Gegenwart von AlCl3 führte zu vernetzten Polymeren, was durch Änderung der Bedingungen vermeidbar war.
Notes:
Linear, soluble polymers were prepared by condensing triphenylamine with diacid chlorides in the presence of zinc chloride at 25°C. or aluminum chloride at 5°C. Polymers were also obtained from condensations of phosgene, thionyl chloride, and dichloromethane with triphenylamine. Substitution occurred in the para-position on only two of the phenyl rings when zinc chloride was used. Substitution on the third ring which resulted in cross-linked polymers occurred in the presence of aluminum chloride but was avoided by modifying the conditions.
