摘要： 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.

摘要： The present invention relates to pipes for the transmission and/or distribution of combustible gases, and liquefied gases, comprising a polyethylene layer and a polyamide inside and/or outside layer. These pipes may advantageously be connected together by adhesively bonded sleeves and thus form medium-pressure and low-pressure gas distribution and transmission networks or else they may be installed inside already existing metal pipes. These pipes may be manufactured by coextrusion.

摘要： The invention relates to a method of preparing polyamides, in which, in a first step, the anionic polymerization of at least one lactam is carried out and then, in a second step, a heat treatment is carried out on the polymer obtained, which has a distribution of the molar masses measured by SEC having a shape close to a Gaussian curve with a high-mass tail, at a high enough temperature and for a long enough time so as to obtain a unimodal distribution of the molar masses.
