Abstract Ethylenically unsaturated polymers containing units with the formula -CH2-C(Y) CH-CH2-, wherein Y is a hydrogen atom, a halogen atom, an alkyl group or an aryl group, are reacted upon chlorosulfonyl isocyanate C102S-N C O, in the absence of oxygen and moisture, between -20*C and +150*C, in a solvent, either without a catalyst, so as to obtain modified polymers containing units with the formula WHEREIN Y has the above meaning and X is SO2Cl or H, or in the presence of a radical-forming initiator, so as to obtain modified polymers containing units with the formula WHEREIN Y has the above meaning, the polymers thus obtained being elastomeric, resinous or fibrous and having improved physical and chemical properties.
