✦ Synopsis


The addition of benzoic acid to the oxirane ring of epoxidized polymers of dienes is limited by side reactions which are promoted by increase of time, temperature, or epoxide concentration. Only high [Acid]/[Epoxide] ratios afford good yields of modification of the epoxidized polymers. a) Partie I: cf. I). b, Equipe de Recherche Associ6e au C.N.R.S. no 311.
