✦ Synopsis

Using the results obtained in part I, we studied the polycondensation of ¢x,to-diphenol oligosulphones with c¢,to-diepoxy oligosiloxanes. Structural study of the resulting copolymers by ~Hand I~C-NMR and by GPC showed that poly(sulphone-b-siloxane)s were formed. The reactions were carried out either in a reactor, in highly concentrated solutions, or in a mixer; the best results were obtained by the second technique. The structure of the block-copolymers was determined.
