Addition of chlorosulfonyl isocyanate to CC bonds in cis ‐1,4‐polyisoprene and reaction of the adduct with NaOH resulted in the formation of a water‐soluble polyelectrolyte with N ‐sulfate and carboxylate groups. The polyelectrolyte showed anticoagulant activity and it was found, just as with heparin, that the activity was related to molecular weight and N ‐sulfate content.
