✦ Synopsis

A~trae~In first part [l] [Eur. Polym. J. 19, 1099 (1983)] the reaction of 4-hydroxybenzoic acid with epoxy groups was studied on models. The present article is devoted to the same reaction, when carried out on poly(butylacrylate-co-glycidylacrylate). It appears that the behaviour of this system is far more complex than that of models. The catalyst is dimethyldodecylamine. Unlike the models, epoxy consumption is more rapid than that of acid; moreover the consumption of phenol is lower than the difference between the consumptions of acid and of phenol. This is due to an intramolecular reaction of oxirane rings and is in agreement with Madec's work on epoxy-carboxy reaction. From these modified copolymers, a polymeric dye was obtained by coupling of a diazonium salt with phenol side-groups. The resulting polymeric dye is able to complex Cu It.
