The selective oxidative cleavage of unsaturated copolymers of isobutene with conjugated diene using ruthenium tetroxide has been carried out, giving various bifunctional oligomers. A comparison between molecular weight determination and microanalysis seems to show that the nearly perfect bifunctiona

The solution properties of graft copolymers having a poly-(methyl methacrylate-co-lauryl methacrylate) backbone and poly-(oxyethylene) branches of different compositions were studied by static and dynamic light scattering methods in ethanol-water mixed solvents. The graft copolymers formed multimole
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
