Abstract
A method of making a polyamide comprises polymerizing a lactam in the presence of an anionic catalyst and, di-e -caprolactam ether. Specified lactams are e -caprolactam, oenantholactam, valerolactam, butyrolactam, a -methyl caprolactam, caprylolactam, dodecyllactam and mixtures thereof. Specified catalysts are lactammetal compounds, e.g. sodium caprolactam, metal alkyls, e.g. diisobutyl aluminium hydride, trietyl aluminium, triisopropyl aluminium and diethyl zinc, the alkali and alkaline earth metals and hydrides, oxides, hydroxides and carbonates thereof and Grignard reagents, e.g. alkyl magnesium bromide and aryl magnesium bromide. Dyes, fillers, e.g. wood meal, carborundum, carbon black, powdered slate, fine coal and coke breeze may be incorporated in the lactam melt.
