In one aspect, the present invention is related to a process for the preparation of an isoolefin polymer comprising repeating units derived from at least one isoolefin, at least one divinyl aromatic monomer and, optionally, additional copolymerizable monomers, wherein the content of unreacted vinyl groups from the aromatic monomer is predicted by means of FTIR measurements. In another aspect, the present invention is related to a process for th e preparation of an isoolefin polymer comprising repeating units derived from at least one isoolefin, at least one divinyl aromatic monomer and, optionally, furthe r copolymerizable monomers, wherein the content of unreacted vinyl groups from the aromatic monomer is predicted by means of FTIR measurements and said prediction is subsequently used to alter at least one process parameter.
