したがって、第１の態様によれば、本発明の目的は、式Ａ／Ｘ１Ｙの、少なくとも２つの別個の単位ＡおよびＸ１Ｙを含むコポリアミドであって、
式中、
－ Ａは、

少なくとも２つの別個の単位ＡおよびＸ１Ｙを含むコポリアミドの、２０℃～４０℃の温度範囲内、特に０℃～４０℃の温度範囲内、とりわけ－１０℃～４０℃の温度範囲内で弾性率が２０％超変動しない組成物を調製するための使用である。
Thus, according to a first aspect, the object of the present invention is a copolyamide comprising at least two distinct units A and X 1 Y of formula A/X 1 Y,
In the formula,
- A is,
a repeating unit obtained by polycondensation of at least one C9 - C18 , preferably C10 - C18 , more preferably C10 - C12 amino acid, or of at least one C9 - C18 , preferably C10 - C18 , more preferably C10 - C12 lactam, or of at least one C4 - C36 , preferably C6 - C18 , preferably C6 - C12 , more preferably C10 - C12 diamine Ca with at least one C4 - C36 , preferably C6 - C18 , preferably C6 - C12 , more preferably C10 - C12 dicarboxylic acid Cb,

The use of a copolyamide comprising at least two distinct units A and X 1 Y for preparing a composition whose modulus does not vary by more than 20% within the temperature range of 20°C to 40°C, in particular within the temperature range of 0°C to 40°C, and more particularly within the temperature range of -10°C to 40°C.
本発明者らは、意外にも、芳香族二酸に基づく繰り返し単位Ａおよび繰り返し単位Ｘ１Ｙを含む半芳香族コポリアミドの選択が、弾性率が温度および湿度の影響下で安定性を示し、２０℃～４０℃の温度範囲内、特に０℃～４０℃の温度範囲内、とりわけ－１０℃～４０℃の温度範囲内で２０％を超えて変動しないだけでなく、処理が、処理中の、低い成形温度、特に１００℃未満、好ましくは９０℃未満、および短いサイクルタイムによって促進される組成物を調製することを可能にすることを発見した。
The inventors have surprisingly discovered that the choice of a semi-aromatic copolyamide comprising repeating units A based on an aromatic diacid and repeating units X 1 Y makes it possible to prepare compositions whose modulus not only exhibits stability under the influence of temperature and humidity and does not vary by more than 20% within the temperature range of 20° C. to 40° C., in particular within the temperature range of 0° C. to 40° C., especially within the temperature range of −10° C. to 40° C., but also whose processing is facilitated by low moulding temperatures, in particular below 100° C., preferably below 90° C., and short cycle times during processing.
