NEW FIBER-FORMING POLYAMIDES,

Abstract

Polyamides have been obtained in yields of 92-95% from the unsaturated 6-dodecene-1, 12-dicarboxylic and 6, 10-hexadecadiene dicarboxylic acid sethylene diamine, hexamethylene diamine and decamethylene diamine. The polyamide from 6-dodecene-1, 12-dicarboxylic acid and hexamethylene diamine yields fiber which after irradiation with gamma rays from Co-60 at a dose rate of 2.7 Mrad/hr., showed a breaking strength of up to 33.1 rkm and an elongation of 23%, compared with values of 20.3 rkm and 25% for the unirradiated fiber.
