✦ Synopsis

Abstract~Cationic polymerization of tetrahydrofuran (THF) initiated by difunctional peroxidic initiators bis(4-bromomethyl benzoyl) peroxide and 2,5-dimethyl 2,5-di(4-bromomethyl benzoyl peroxy)hexane is described. Poly-THF samples possessing peroxidie groups thus obtained were used in the polymerization of styrene at 80 ° to obtain THF-styrene block copolymers in high yields.

## Abstract The cationic polymerization of isobutylene with weak Lewis acids, such as BBr~3~ and FeBr~3~, has been studied. These halides are unable to induce individually the polymerization in nonpolar solvents, such as heptane or toluene, or they only initiate the polymerization to low conversion
