摘要： A composite closure with a side seal proportioning lip is disclosed, with the closure including an outer plastic closure cap, and a plastic sealing liner positioned adjacent a top wall portion of the cap. The sealing liner includes a central disc-shaped portion, and an integral relatively thick, annular sealing bead portion. The closure is thus configured to effect a "top/side seal" with an associated container. The construction includes an annular liner-retaining lip having a relatively flexible annular inner edge portion which coacts with the sealing bead portion of the liner to self-adjust and proportion the degree of sealing engagement between the sealing bead portion of the liner and the associated container.
摘要翻译：公开了一种具有侧密封比例的唇缘的复合封闭件，封闭件包括外部塑料封闭盖和邻近盖的顶壁部分定位的塑料密封衬套。密封衬套包括中心盘形部分和一体的相对厚的环形密封胎圈部分。因此，闭合件被配置成利用相关联的容器来实现“顶部/侧面密封”。该结构包括具有相对柔性的环形内边缘部分的环形衬垫保持唇缘，其与衬垫的密封胎圈部分共同作用以自调节并且比较衬套的密封胎圈部分与相关容器之间的密封接合程度。

摘要： Preparation of butyl rubber based graft co-polymers from halobutyl elastomers using phase transfer catalysts in the presence of a solution of an alkali metal salt of an oxygen or sulfur nucleophile that is bound to a polymeric substrate. Graft co-polymers can be produced of a butyl polymer (isobutene-coisoprene) and polymeric substrates such as polyethylene, polypropylene, polystyrene, polybutadiene, polysilanes, polysiloxanes, polyethylene glycol, polyethylene oxide, polyphosphazenes, polyferrocenes or their hybrids.

摘要： The present invention provides a process for preparing a filled halobutyl elastomer, which includes mixing a halobutyl elastomer with at least one mineral filler and at least one phosphine modifier and optionally curing the filled elastomer with sulfur or other curative systems. Filled halobutyl elastomers prepared according to the present invention possess improved levels of filler dispersion which results in a reduction in the hardness of the compound and an increased tensile strength.
摘要翻译：本发明提供一种制备填充的卤代丁基弹性体的方法，其包括将卤代丁基弹性体与至少一种矿物填料和至少一种膦改性剂混合，并任选地用硫或其它固化体系固化填充的弹性体。根据本发明制备的填充的卤代丁基弹性体具有提高的填料分散体水平，导致化合物的硬度降低和拉伸强度的增加。
