Abstract[English]
A heterogeneous catalyst composition for preparing a highly-reactive polyisobutylene from isobutylene may include a Lewis acid, a support, an initiator, and optionally an electron donor. A method of polymerizing isobutylene to a highly- reactive polyisobutylene may include a heterogeneous catalyst composition including include a Lewis acid, a support, an initiator, and optionally an electron donor.[French]
