    • Sealing gaskets are provided for forming a seal between the door of an appliance and the cabinet of the appliance when the door of the appliance is closed onto the cabinet of the appliance. The gaskets are adapted to be mounted to the door of the appliance and comprise a first bellows chamber that can be compressed when the door of the appliance is closed onto the cabinet of the appliance, a pocket contiguous with the first bellows chamber for holding a magnet and a second bellows chamber adapted to be nearer the cabinet of the appliance than the pocket and engage the cabinet of the appliance prior to the pocket engaging the cabinet of the appliance when the door of the appliance is closed onto the cabinet of the appliance. Several embodiments of the sealing gaskets are disclosed.

    • A method for purifying bisimides is provided. In one aspect, purified oxybisphthalimides, intermediates useful in the preparation of polyetherimides are provided. In one embodiment, a first solution containing a bisimide compound, a solvent, and a phase transfer catalyst is contacted with a solid inorganic adsorbent material having a total pore volume of about 0.5 milliliters/gram or greater and a cumulative pore volume distribution of about 20 percent or greater of particles having a pore diameter in a range between about 3 nanometers and about 20 nanometers. The solution containing the bisimide compound is then separated from the solid inorganic adsorbent material to provide a purified bisimide compound which is substantially free of the phase transfer catalyst. The purification technique is especially valuable for preparing high purity oxybisphthalimides, such as 4,4′-oxybis(N-methylphthalimide), which are substantially free of residual phase transfer catalyst.
    • 提供了一种纯化双酰亚胺的方法。 一方面,提供了纯化的氧联双苯二酰亚胺,可用于制备聚醚酰亚胺的中间体。 在一个实施方案中,将含有双酰亚胺化合物,溶剂和相转移催化剂的第一溶液与总孔体积为约0.5毫升/克或更大并且累积孔体积分布约为20的固体无机吸附材料接触 百分比或更大的具有在约3纳米和约20纳米之间的孔径的颗粒。 然后将含有双酰亚胺化合物的溶液与固体无机吸附剂材料分离,以提供基本上不含相转移催化剂的纯化双酰亚胺化合物。 纯化技术对于制备基本上不含残余相转移催化剂的4,4'-氧双(N-甲基邻苯二甲酰亚胺)的高纯度氧联双苯二酰亚胺是特别有价值的。
