<p>A process is provided for producing a low molecular weight isoolefin polymer by contacting at conversion conditions a higher molecular weight saturated isoolefin polymer, for example, polyisobutylene or a copolymer of a C4 to C7 isoolefin and a para-alkylstyrene, in the melt phase, with an initiator, such as an oxygen-containing gas, an organic peroxide or an azo compound.</p> |
