Beschreibung
Zusammenfassung:	The invention relates to a method for continuously producing a copolyamide by copolymerizing at least one lactam (A) and a monomer (M), said method comprising the following steps: a) mixing at least one lactam (A) with a monomer (M) at a temperature of 60 to 150 DEG C, and b) passing the mixture obtained in step a) from the top down through a vertical polymerization tube at a temperature at which the polyamide is formed to obtain the copolyamide, wherein said monomer (M) comprises at least one C32-C40 dimer acid (B1) and at least one C4-C12 diamine (B2) and optionally at least one C4-C20 diacid (B3). 一种使至少一种内酰胺(A)和单体(M)共聚来连续制备共聚酰胺的方法，所述方法包含以下步骤：a)将至少一种内酰胺(A)与单体(M)在60至150℃的温度下进行混合，和b)使步骤a)中获得的混合物在形成聚酰胺的温度下从顶部向下通过立式聚合管而获得共聚酰胺，其中所述单体(M)包含至少一种C32-C40二聚酸(B1)和至少一种C4-C12二胺(B2)和任选地至少一种C4-C20二酸(B3)。
