    Abstract: The invention relates to a method for reducing the content of an aliphatic, monounsaturated amine (III) in a mixture (IV) containing an aminonitrile (I) or a diamine (II), or mixtures thereof and an amine (III). Said method is characterised in that a) mixture (IV) is reacted with an anionic nucleophile (V) in a quantity ranging between 0.01 and 10 mol per mol of amine (III) in mixture (IV) to obtain a mixture (VI). The invention is also characterised in that b) aminonitrile (I) or diamine (II) or mixtures thereof are removed by distillation from mixture (VI), at a temperature ranging between 50 and 170 DEG C and a pressure of between 0.5 and 100 kPa.

    Abstract: The invention relates to a method for producing a polymer. Said method is characterized as follows: a) a mixture (I) containing 6-aminocapronitrile and water is converted into a mixture (II) containing caprolactam, ammonia, water, high boilers and low boilers in the presence of a catalyst; then b) the ammonia is removed from mixture (II) to obtain a mixture (III) containing caprolactam, water, high boilers and low boilers; subsequently c) the water is completely or partially eliminated from mixture (III) to obtain a mixture (IV) containing caprolactam, high boilers and low boilers; and finally d) mixture (IV) is subjected to a polymerization reaction. The invention also relates to a polymer obtained according to said method, to its use in the production of fibres, flat material and moulded bodies that are obtained using a polymer of this type.
