FIBER-FORMING COPOLYAMIDE FROM 2-METHYL-PENTAMETHYLENE DIAMINE

摘要

A fiber-forming copolyamide consisting essentially of between about 60 and about 99.5 mole % hexamethylene adipamide units and between about 0.5 and 40 mole percent 2-methyl-pentamethylene adipamide units, the copolyamide having an RV greater than about 25, and a melting point of greater than about 220 DEG C.
