概要

Copolyamides containing 2-methylpiperazine were obtained through condensation polymerization of either 2-methylpiperazinium terephthalate or adipate withcaprol-actam or hexamethylene diammonium adipate. The usual V-shape relationships-were observed between the melting points of the copolyamides and their composi-tions. The melt-spun fibers, prepared by using Koka Flow Tester, showed higher moisture regain than Nylon 6 and 66.
