Anhydrous polymeric metal terephthalate and isophthalate fibers are disclosed and a method for making them wherein said metal is selected from the group consisting of calcium, barium, magnesium and zinc, said fibers have an average aspect ratio of greater than about 5:1. These fibers are very useful additives serving as property extenders and/or reinforcing agents in polymeric compositions and articles molded therefrom.

Polymeric metal terephthalate and isophthalate fibers

Hydrotalcites are disclosed as stabilizers for vinyl halide resins where the BET has a specific surface area of at least about 40 m.sup.2 /g, preferably about 50 to 60 m.sup.2 /g.

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.

High performance engineering polymer compositions

Ruthenium aromatic polycarboxylates from the class consisting of ruthenium isophthalate, ruthenium trimesate, ruthenium trimellitate, ruthenium pyromellitate and ruthenium 5-sulfonate-1,3-isophthalate have been prepared and have been found to be especially suitable as semiconductors.

Ruthenium aromatic polycarboxylates

Stannic terephthalate has been prepared and has been found to have an unusually high dielectric constant, electrical and thermal stabilities, and high volume resistivity that make this compound ideal for use as a capacitor dielectric.
