| Résumé : |
In this study, polyblend of polyamide 6 (PA6) with ethylene vinyl acetate (EVA) are investigated. For this purpose, PA6 chips were blended with EVA whose composition varies from 0,1 and 4% by weight. The resulting data indicates that at constant draw ratio, with increase in EVA content, there is decrease in density, optical birefringence, crystallinity, tenacity and modulus where as an increase in dye uptake and percentage stain. PA6 and EVA show good compatibility towards each other as evidenced by DSC and SEM studies. Also, the 2% of EVA blend is a good choice in increasing the dye ability of PA6 at a low cost. |
