%X The bromization of poly(4-methyl-pentene-1),tactic and atacticpolypropylene was investigated.The substitution proceeds by free-radical mechanizm.Thesubstitution of bromine atoms is on the tertiary carbon of main-chain of the polymersprimally.The solubleness and physical properies of the three polymers were changed bybromization.Measurement results of oxygen enrichment performence of the threebromizated polymers show that permeability coefficients of O_2,N_2 decrease and separa-tion coefficients increase.These materials are expected to meet some special membranes forseparation of gas.
