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 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.

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 the use of a composition that contains from 70 to 91 wt % of at least one semi-crystalline polyamide, from 5 to 25 wt % of a polyolefin having an epoxy, anhydride or acid function introduced by grafting or copolymerization, and from 4 to 20 wt % of a plasticizer in the production of flexible pipes used in the exploitation of crude oil or gas deposits under the sea that comprises at least one layer obtained from such a composition.
