Process for lowering the crystallization temperature of partially crystalline polyamides, polyamide molding composition produced thereby and use of polyfunctional transesterifiable organic phosphonites, organic phosphites, organic phosphates or mixtures thereof for lowering the crystallization temperature, for crosslinking and / or branching of partially crystalline polyamides

摘要

The present invention relates to a process for lowering the crystallization temperature of partially crystalline polyamides in which at least one partially crystalline polyamide or mixtures of at least two partially crystalline polyamides is mixed with at least one polyfunctional transesterifiable organic phosphonite, organic phosphite, organic phosphate or mixtures of at least two of the aforementioned compounds is, the mixture formed is converted into a melt, wherein a transesterification of the at least one polyfunctional transesterifiable organic phosphonite, organic phosphite, organic phosphate or mixtures of at least two of the aforementioned compounds with simultaneous transamidation of the at least one partially crystalline polyamide, and finally the mixture is cooled.
