    • The present disclosure provides novel methods of producing a composition, such as, but not limited to, a polyimide composition. The methods in their most general form comprise providing a workpiece, suspending the workpiece and subjecting the suspended workpiece to processing such that the workpiece undergoes a transformation from a first state to a second state. By maintaining the workpiece in a suspended state during processing, processing-related defects are reduced or eliminated. Using such methods, the present disclosure provides compositions that are have no or reduced processing-related defects. In addition, the compositions are more consistent in chemical and physical properties and are cheaper and more economical to produce (since less product is rejected as unsuitable).
    • 本公开提供了制备组合物的新方法,所述组合物例如但不限于聚酰亚胺组合物。 其最通用形式的方法包括提供工件,悬挂工件并对悬挂的工件进行加工,使得工件经历从第一状态到第二状态的转变。 通过在加工过程中将工件保持在悬挂状态,可减少或消除与加工相关的缺陷。 使用这些方法,本公开提供了没有或减少与加工相关的缺陷的组合物。 此外,组合物在化学和物理性质上更一致,并且制造成本更低廉并且更经济(因为较少的产品被拒绝为不合适)。

    • The present disclosure provides a novel suspension device used in producing a composition, such as, but not limited to, a polyimide composition. The suspension device in its most general form comprises a support element and an attachment element. The attachment element is in communication at one of its ends with the support element and at the other with a workpiece, such as a poly(amic acid) or polyimide workpiece. The suspension device may further comprise additional elements. The suspension device maintains the workpiece in a suspended state during processing so as to reduce or eliminate processing-related defects.
    • 本公开提供了一种用于制备组合物的新型悬浮装置,所述组合物例如但不限于聚酰亚胺组合物。 其最通用形式的悬挂装置包括支撑元件和附接元件。 附接元件在其一个端部处与支撑元件连通,另一端与工件(例如聚(酰胺酸)或聚酰亚胺工件)连通。 悬挂装置还可以包括附加元件。 悬挂装置在处理期间将工件保持在悬挂状态,以便减少或消除与处理相关的缺陷。

    • The present disclosure describes comprises a polyimide composition comprising at least one diamine monomer and at least two dianhydride monomer types, at least two diamine monomer types and at least one dianhydride monomer at least two diamine monomer types and at least two dianhydride monomer types. In one embodiment, the diamine monomers are 2,2-bis[4-(4aminophenoxy)phenyl]-hexafluoropropane (BDAF) or 4,4′-diaminobenzanilide (DABA) or combinations of the foregoing and the dianhydride monomers are 4,4′-(hexafluoroisopropylidene)di-phthalicanhydride (6-FDA) and 3,3′,4,4′-biphenyltetracarboxylic acid dianhydride (s-BDPA) or combinations of the foregoing. The polyimide compositions described herein have controllable and variable properties, such as but not limited to CTE, allowing the use of the polyimide compositions in a wide variety of applications.
