Abstract
The invention relates to a method for storage and for transport of polyamide granulate which comprises at least one amorphous or microcrystalline polyamide. By means of this novel method, yellowing during further processing to form the moulded article can be avoided or at least reduced. Likewise, the invention relates to a corresponding container in which the polyamide granulate is stored. The invention also relates to correspondingly stored or transported polyamide granulate and also moulded articles produced therefrom.
