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

The synthesis of poly(butadiene-b-sulphone) by two methods was described in part I (Eur. Polym. J. 20, 305 [1]). The results obtained by reaction of ~,c0-dicarboxylic oligobutadiene with ct,co-diepoxy oligosulphones are reported here. The kinetics of the reaction are studied on models; reaction orde
