Title (EN) HIGH MOLECULAR WEIGHT POLYAMIDES AND COPOLYAMIDES WITH UNIFORM RV AND LOW GEL CONTENT
(FR) POLYAMIDES DE MASSE MOLÉCULAIRE ÉLEVÉE ET COPOLYAMIDES À RV UNIFORMES ET FAIBLE TENEUR EN GEL
Abstract:
(EN) A customizable polyamide polymer, in particular Nylon 66, Nylon 6, and copolyamides, having a high molecular weight, excellent color, and low gel content is disclosed. In particular, disclosed is a polymer having a relative viscosity greater than 50 as measured in a 90% strength formic acid solution; consistent viscosity with a standard deviation of less than 1; a gel content no greater than 50 ppm as measured by insolubles larger than 10 micron; an optical defect content of less than 2,000 parts per million (ppm) as measured by optical control system (OCS). The polymer can be made into monofilaments or a multifilament yarn. Also disclosed is a process of producing the polymer using in-line vacuum finishing technology in the absence of steam or other gases in the second, or post condensation, step of the polymer process.
(FR) La présente invention concerne un polymère polyamide personnalisable, notamment du Nylon 66, du Nylon 6, et des copolyamides, présentant une masse moléculaire élevée, une excellente couleur et une faible teneur en gel. En particulier, la présente invention concerne un polymère présentant une viscosité relative supérieure à 50, telle que mesurée dans une solution d'acide formique à 90 % de résistance; une viscosité cohérente avec un écart-type inférieur à 1; une teneur en gel inférieure ou égale à 50 ppm, mesurée par des matières insolubles de taille supérieure à 10 microns; une teneur en défaut optique inférieure à 2000 parties par million (ppm) mesurée par un système de commande optique (OCS). Le polymère peut être transformé en monofilaments ou un fil multifilament. La présente invention concerne également un procédé de production du polymère en utilisant une technologie de finition sous vide en ligne en l'absence de vapeur ou d'autres gaz au cours de la seconde étape ou de l'étape de post-condensation, du processus de polymère.
