    Abstract: An improved copolyamide is derived from terephthalic acid, at least one straight-chain alkanedioic acid having from 8 to 14 carbon atoms, the terephthalic acid constituting from 50 to about 90 mole percent of the acids, and at least one straight-chain alpha, omega-alkanediamine having from 6 to 14 carbon atoms. This copolyamide is useful as a molding resin and in the production of fibers.

    Abstract: Substantially amorphous, optically clear polyamides are produced from a bis(4-aminocyclohexyl)methane or methyl derivative thereof and a bis(carboxyphenyl)methane or methyl derivative thereof. Copolyamides having desirable processing properties are produced by polymerizing the above monomers and at least one straight chain dicarboxylic acid as an additional monomer. The resulting polymers are useful as fibers as well as molding resins.

    Abstract: A salt of dicarboxylic acid and diamine, at least 50 mole percent of the dicarboxylic acid being terephthalic acid, is condensed to form a polyterephthalamide by heating the salt to a temperature in the range of about 200*C. to about 230*C. and maintaining the salt at that temperature for about 1/2 hour to about 6 hours before increasing the temperature of the salt to at least 250*C. In one specific embodiment the salt contains from about 2 to about 8 mole percent excess acid.
