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 polymeriz

## Abstract The cationic polymerization of styrene and __p__βmethylstyrene has been initiated in the presence of trimethylsilyl trifluoromethanesulfonate. In a dry system, no polymerization was observed. In wet systems, polymers were formed in agreement with earlier reports. In the presence of hind
Cationic polymerization of styrene(St) initiated by phosphorus trichloride(PC13) in nitrobenzene was carried out at 30 Β°. The initial rate was proportional to [St] 2 and [PCl3]. The overall activation energy was about 10.4 kcal/mole. The rate and the degree of polymerization were enhanced with incre
