    • Bis(halophthalimides) are prepared in a solvent such as ortho-dichlorobenzene or anisole, by a reaction at a temperature of at least 150° C. between at least one diamine compound and at least one halophthalic anhydride in the presence of imidization catalyst. The reaction produces a vapor stream comprising solvent and water formed as a by-product of the imidization reaction. A suitable vapor handling system comprising a partial reflux condenser is used to recycle the solvent, maintain the reactant concentration, conduct the reaction at a higher temperature, and effect more efficient conversion of reactants to product bis(halophthalimides). Reaction conditions disclosed may also be used to prepare organic polyimides.
    • 通过在酰亚胺化催化剂存在下,在至少一种二胺化合物和至少一种卤代邻苯二甲酸酐之间的至少150℃的温度下进行反应,在溶剂如邻二氯苯或苯甲醚中制备双(卤代邻苯二酰亚胺)。 反应产生包含作为酰亚胺化反应的副产物形成的溶剂和水的蒸气流。 使用包含部分回流冷凝器的合适的蒸汽处理系统来回收溶剂,保持反应物浓度,在较高温度下进行反应,并且使反应物更有效地转化成产物双(卤代​​邻苯二酰亚胺)。 所公开的反应条件也可用于制备有机聚酰亚胺。

    • High heat polyethersulfone compositions are provided which possess unexpectedly high glass transition temperatures. The polyethersulfone compositions comprise structural units derived from fluorenone bisphenols such as 9,9-bis(4-hydroxyphenyl)fluorene, and structural units derived from at least one biphenyl-bissulfone such as 4,4′-bis((4-chlorophenyl)sulfonyl)-1,1′-biphenyl. The novel polyethersulfone compositions may further comprise structural units derived from one or more biphenols such as 4,4′-biphenol, bisphenols such as BPA, or other electrophilic sulfone monomers, such as bis(4-chlorophenyl)sulfone. In one embodiment, the polyethersulfone composition of the present invention comprises structural groups derived exclusively from 9,9-bis(4-hydroxyphenyl)fluorene and 4,4′-bis((4-chlorophenyl)sulfonyl)-1,1′-biphenyl and exhibits a single glass transition of greater than 300° C.
    • 提供了具有出人意料的高玻璃化转变温度的高热聚醚砜组合物。 聚醚砜组合物包含衍生自芴酮双酚的结构单元如9,9-双(4-羟基苯基)芴,以及衍生自至少一种联苯基 - 砜的结构单元,例如4,4'-双((4-氯苯基)磺酰基 )-1,1'-联苯。 新型聚醚砜组合物还可以包含衍生自一种或多种双酚的结构单元,例如4,4'-联苯酚,双酚如BPA或其它亲电子砜单体如双(4-氯苯基)砜。 在一个实施方案中,本发明的聚醚砜组合物包含仅由9,9-双(4-羟基苯基)芴衍生的结构基团和4,4'-双((4-氯苯基)磺酰基)-1,1'-联苯 并显示大于300℃的单一玻璃化转变。
