METHODS OF PRODUCING CAST POLYAMIDES, STABLE DURING STORAGE OF MIXTURES OF ACTIVATORS AND CATALYSTS, AS WELL AS USE THEREOF TO PRODUCE CAST POLYAMIDES

摘要

FIELD: chemistry.SUBSTANCE: invention relates to method of producing cast polyamides by polymerisation of lactams in presence of at least one activator and at least one catalyst. Invention also relates to mixture from biuret as activating agent in concentration of up to maximum 5% and caprolactam, having stability during storage for at least 6 weeks. Mixture is used for production of cast polyamides.EFFECT: technical result is obtaining activators and catalysts mixtures without solvent and obtaining of permanent quality cast polyamides.7 cl, 3 tbl
