    • Colpolyamides resulting from the polycondensation of a mixture of (a) dodecanelactam (L12) or of 12-aminododecanoic acid (A12) and of (b) 11-aminoundecanoic acid (A11) are characterized in that the monomer L12 or A12 represents 1 to 15% or 85 to 99% by weight of the mixture, and the copolyamides have melting points (mp) as a function of the composition, the units originating from the monomer A12 and L12 being in a majority or minority respectively:(1) A12 or L12 is a majority: mp (.degree. C.).gtoreq.176-0.567.times.(% A11)(2) A12 or L12 is a majority: mp (.degree.).gtoreq.187-0.5.times.(% A12 or L12),the melting points being determined by taking the peaks of the exotherm signals obtained in differential thermal analysis with a rate of heating of 10.degree. C./minute for the second heating run. Such copolyamides have a property of resilience at low temperature and a property of improved suppleness, especially when plasticizer is added to them. Their ductile/brittle transition temperature is shifted towards a lower temperature.
    • 由(a)十二内酰胺(L12)或12-氨基十二烷酸(A12)和(b)11-氨基十一烷酸(A11)的混合物缩聚得到的共聚酰胺的特征在于,单体L12或A12表示1〜15 %或85至99重量%,共聚酰胺具有作为组合物的函数的熔点(mp),源自单体A12和L12的单元分别为多数或少数:(1)A12或 L12为多数:mp(℃)> / = 176-0.567x(%A11)(2)A12或L12为多数:mp(℃)= 187-0.5倍(%A12或L12) 通过在差热分析中获得的放热信号的峰值以10℃/分钟的速率进行第二次加热运行来确定熔点。 这种共聚酰胺在低温下具有回弹性能,并具有改善柔软性的特性,特别是当添加增塑剂时。 它们的延性/脆性转变温度向较低的温度转移。
