摘要: This invention concerns a process for obtaining polyamides in which the polymer is mixed with one or more tertiary alcohols with the formula:
WHERE R1, R2 and R3 are hydrocarbon radicals, preferably aliphatic radicals. In this process, the polyamide is obtained by anionic polymerization of lactams in an anhydrous medium, in the presence of alkaline catalysts, usually sodium catalysts, and possible activators.
