    • The present invention generally relates to singly-terminated polyisobutylene (PIB) compounds, and to a process for making such compounds. In one embodiment, the present invention relates to singly-terminated polyisobutylene compounds that contain only one primary alcohol, amine, or methacrylate group as the single-terminating group. In another embodiment, the present invention relates to singly-terminated polyisobutylenes carrying exactly one terminal alcohol, amine, or methacrylate group, where such singly-terminated polyisobutylenes have a number average molecular weight of about 500 to about 5000 grams per mole. In still another embodiment, the present invention relates to singly-terminated polyisobutylene compounds that can be used to synthesize polyurethanes, to polyurethane compounds made via the use of such polyisobutylene compounds, and to processes for making such compounds.
    • 本发明一般涉及单封端的聚异丁烯(PIB)化合物,以及制备这些化合物的方法。 在一个实施方案中,本发明涉及单一封端的聚异丁烯化合物,其仅含有一个伯醇,胺或甲基丙烯酸酯基团作为单末端基团。 在另一个实施方案中,本发明涉及具有一个末端醇,胺或甲基丙烯酸酯基团的单末端聚异丁烯,其中这种单端封聚异丁烯的数均分子量为约500至约5000克/摩尔。 在另一个实施方案中,本发明涉及可用于合成聚氨酯的单末端聚异丁烯化合物,涉及通过使用这种聚异丁烯化合物制备的聚氨酯化合物,以及制备此类化合物的方法。
