## Abstract Styrene isoprene styrene copolymers (SIS) modified by epoxidizing were investigated in order to obtain adhesive materials. Influences of experimental parameters (concentrations, solvents, compositions of SIS) are shown for epoxidation with monoperoxyphtalic acid at a yield of modificati
If a block-copolymer of styrene and ethylene oxide is mixed with a solvent which exhibits preferential affinity for the polystyrene block, birefringent gels are obtained. The structure of these gels is lamellar and the layers of unsolvated polyethyleneoxide are crystalline. In the present work, the
