    摘要: In various embodiments, the present invention is directed to new low cost initiator compositions for use with the production of well-defined telechelic PIBs (by LC+P of isobutylene). In various other embodiments, the present invention is directed to methods for using these novel compositions as initiators for isobutylene (IB) and other cationically polymerizable monomers, such as styrene and its derivatives. In still other embodiments, the present invention is directed to structurally new, allyl (and chlorine) telechelic PIBs formed from these new initiator compositions and their derivatives (in particular, hydroxyl telechelic PIB and amine telechelic PIB). In yet other embodiments, the present invention is directed to structurally new polyurethanes, polyureas, and polyurethane ureas made using telechelic PIBs formed from these new initiator compositions.

    摘要: A vent cover assembly is disclosed, such as for a floating or fixed floor. Example vent cover assemblies may include a support plate configured to be secured over a duct, and a flush mount vent cover. The support plate may define a plurality of first airflow apertures configured to permit airflow from the duct through the support plate. The vent cover may define a second plurality of airflow apertures that are positioned in the vent cover such that the second plurality of airflow apertures are aligned with the first airflow apertures when the vent cover is in a first installed position overlying the support plate. The vent cover may obstruct the first airflow apertures when the vent cover is in a second installed position overlying the support plate.
