Abstract

Le procédé selon l'invention consiste à extruder un polymère principalement cristallin en 1 pour obtenir un filament extrudé 2 qui est enroulé sur un tambour 3, à étirer le filament extrudé à une température qui est considérablement inférieure au point de fusion du polymère, la température d'étirage pouvant être inférieure de 120 degrés C au point de fusion, et à refroidir le filament étiré dans un bain à une température qui est inférieure d'au moins 20 degrés C à la température d'étirage. Le procédé de l'invention peut s'appliquer à des polymères hydrocarbonés tels que le polyéthylène et le polypropylène ou à des polymères hydrocarbones substitués par de l'oxygène, tels que l'oxyde de polyéthylène, le polyoxyméthylène, le polyacétaldéhyde, ainsi qu'aux polyamides, polyesters linéaires et polymères fluorés.The method according to the invention consists of extruding a mainly crystalline polymer in 1 to obtain an extruded filament 2 which is wound on a drum 3, in drawing the extruded filament at a temperature which is considerably lower than the melting point of the polymer, the temperature drawing which may be 120 degrees C below the melting point, and cooling the drawn filament in a bath to a temperature which is at least 20 degrees C below the drawing temperature. The process of the invention can be applied to hydrocarbon polymers such as polyethylene and polypropylene or to hydrocarbon polymers substituted with oxygen, such as polyethylene oxide, polyoxymethylene, polyacetaldehyde, as well as polyamides, linear polyesters and fluoropolymers.
