METHOD FOR LOWERING THE CRYSTALLIZATION TEMPERATURE OF SEMICRYSTALLINE POLYAMIDES, POLYAMIDE MOLDING COMPOUND PRODUCED THEREBY, AND USE OF ORGANIC PHOSPHORUS COMPOUNDS TO LOWER THE CRYSTALLIZATION TEMPERATURE
METHOD FOR LOWERING THE CRYSTALLIZATION TEMPERATURE OF SEMICRYSTALLINE POLYAMIDES, POLYAMIDE MOLDING COMPOUND PRODUCED THEREBY, AND USE OF ORGANIC PHOSPHORUS COMPOUNDS TO LOWER THE CRYSTALLIZATION TEMPERATURE
The invention relates to a method for lowering the crystallization temperature of semicrystalline polyamides, wherein at least one semicrystalline polyamide or mixtures of at least two semicrystalline polyamides are mixed with at least one polyfunctional transesterification-capable organic phosphonite, organic phosphite, organic phosphate or mixtures of at least two of the previously mentioned compounds, the formed mixture is converted into a melt, wherein the at least one polyfunctional transesterification-capable organic phosphonite, organic phosphite, organic phosphate or the mixtures of at least two of the previously mentioned compounds are transesterified, with simultaneous transamidation of the at least one semicrystalline polyamide, and finally the mixture is cooled.
