Abstract
Novel polyamides are prepared by reacting a dicarboxylic acid with 1,4-cyclohexane-bis(.beta.-ethylamine). Unique properties are obtained where the dicarboxylic acid is 1,4-cyclohexane diacetic acid. The polymers of this invention are distinguished from the prior art in that they exhibit unexpectedly high melting points and crystallinity. Thence they are suitable for use in fibers as well as molding and other general polyamide applications.
