The present invention relates to a method for producing a crosslinked polyamide (vP) in which a melt (S) containing at least one polyamide (P) which contains furan units and containing at least one dienophile is provided at a first temperature T1 and the melt (S) is then cooled to a second temperature T2 which is lower than the melting temperature TM of the at least one polyamide (P) in order to obtain the crosslinked polyamide (vP). In addition, the present invention relates to a crosslinked polyamide (vP) obtainable by means of the method according to the invention. 本发明涉及种制备交联聚酰胺(vP)的方法，其中在第温度T下提供熔体(S)，所述熔体(S)包含至少种含有呋喃单元的聚酰胺(P)，和包含至少种亲二烯体，然后将所述熔体(S)冷却至低于至少种聚酰胺(P)的熔融温度T的第二温度T，从而获得交联聚酰胺(vP)。此外，本发明涉及种可通过本发明的方法获得的交联聚酰胺(vP)。
