Beschreibung
Zusammenfassung:	A base polyamide composition comprising a nylon mixture having caprolactam units from 1 wppb to 50 wppm catalyst composition; and greater than 0.75 wt% residual caprolactam, wherein the base polyamide composition has a delta end group level ranging from 30 µeq/gram to 90 µeq/gram. L'invention concerne une composition de polyamide de base comprenant un mélange de nylon comprenant des motifs caprolactame de 1 ppb en poids à 50 ppm en poids de composition de catalyseur ; et plus de 0,75 % en poids de caprolactame résiduel, la composition de polyamide de base ayant une teneur en groupe terminal delta allant de 30 µéq/gramme à 90 µéq/gramme.
