Abstract:
In an embodiment, the present invention provides a process for the liquid phase polymerization of isobutylene to manufacture highly reactive PIB oligomers having Mn under 1000, using a catalyst composition comprising a Friedel-Crafts catalyst and a complexing agent, in the presence of a chain transfer agent. The process advantageously uses short residence times for the isobutylene in the polymerization reaction zone as well as a chain transfer agent selected from: α-DIB and β-DIB and mixtures thereof.
