Abstract:

A new method for drawing Nylon 6 has been developed using iodine as a reversible plasticizer. This is based on the ability of the alpha-crystals is fully transform to gamma-crystals by treatment with an aqueous KI3 solution. Drawing is performed on the intermediate Nylon 6-1 complex and iodine is subsequently removed with sodium thiosulfate to generate back a transparent, drawn Nylon 6. At 55 C, a 790 elongation has been obtained, considerably higher than previously reported for Nylon 6. A dynamic mechanical study of the undrawn complex showed an alpha-transition at 41-53 C. Above this temperature, it is rubbery and thus readily drawn. Originator supplied keywords include Nylon 6 iodine reversible plasticizer drawing Nylon 6-1 complex Dynamic mechanical X-ray diffraction Crystallization Monoclinic.
