<p>A process is disclosed for producing a functionalised polyisobutene (PIB) derivative, which comprises reacting a PIB with hydrogen bromide, and then reacting the resultant PIB bromide so as to displace at least one bromine atom with another functional group. Very low levels of residual halogen in the final product are achieved using this process compared with known chlorination processes, particularly if the PIB has a high percentage of vinylidene C=C bonds</p> |
