摘要: The present invention generally relates to polyisobutylene-based polyurethanes, polyureas and/or polyurethane-polyureas, and a process for making such compounds. In one embodiment, the polyurethane-polyureas also include at least flexible hydrogen bond acceptor chain extender (HACE). another amine telechelic hydroxyl polyisobutylenes are utilized with (HACE) produce having various desired mechanical properties in combination oxidative/hydrolytic stability.
