The invention relates to block polymers, for example, arborescent copolymer compounds, and to methods of making and purifying such compounds. In one embodiment, the invention relates to arborescent polymer compounds that contain one or more styrene polymeric blocks in combination with one or more isobutylene polymeric blocks. In another embodiment, the invention relates to methods for purifying arborescent polymer compounds that contain at least one styrene polymeric block in combination with at least one isobutylene polymeric block.
La présente invention concerne des polymères blocs, par exemple des composés copolymères arborescents, ainsi que des méthodes de synthèse et de purification de tels composés. Dans un mode de réalisation, la présente invention concerne des composés polymères arborescents qui contiennent un ou plusieurs blocs polymères styréniques combinés à un ou plusieurs blocs polymères isobutyléniques. Dans un autre mode de réalisation, la présente invention concerne des méthodes de purification de composés polymères arborescents qui contiennent un ou plusieurs blocs polymères styréniques combinés à un ou plusieurs blocs polymères isobutyléniques.
