    • High performance engineering polymer (HPEP) compositions are disclosed containing a HPEP and a polymeric polyvalent metal aromatic polycarboxylate where the polymeric carboxylate is dispersible, non-migratable, non-extractable and heat stable at processing temperatures of the HPEP. The compositions offer the physical properties of high mechanical strength, durability, toughness, chemical resistance and high temperature performance, among others. The engineering polymers are wholly aromatic polymers having aromatic rings forming the main chain of the polymer and devoid of methylene groups in the main chain. Polymeric metal carboxylates such as calcium terephthalate are employed as the high temperature additive in an effective amount for extending the engineering polymer while substantially maintaining or improving its engineering properties.
    • 公开了包含HPEP和聚合多价金属芳族聚羧酸酯的高性能工程聚合物(HPEP)组合物,其中聚合羧酸酯在HPEP的加工温度下是可分散的,不可迁移的,不可萃取的和热稳定的。 该组合物提供具有高机械强度,耐久性,韧性,耐化学性和高温性能的物理性能等。 工程聚合物是具有形成聚合物主链并且在主链中没有亚甲基的芳环的全芳族聚合物。 使用聚合金属羧酸盐如对苯二甲酸钙作为有效量的高温添加剂用于延伸工程聚合物,同时基本上保持或改善其工程性能。
