Abstract
(EN)
[PROBLEMS] To provide a semi-aromatic polyamide resin having high residence stability, hot water resistance and chemical resistance and also having excellent adhesion property to and compatibility with other resin or the like. [MEANS FOR SOLVING PROBLEMS] The semi-aromatic polyamide resin has dicarboxylate units in which aromatic dicarboxylate units comprise 50 to 100 mol% of the dicarboxylate units and diamine units in which aliphatic diamine units having 9 to 13 carbon atoms comprises 60 to 100 mol% of the diamine units. In the resin, at least 10% of the terminal groups present in the molecular chain are end-capped with an end-capping agent, and the amount of the terminal amino groups present in the molecular chain falls within the range from 60 μ-equivalents/g to 120 μ-equivalents/g inclusive and satisfies the equation: [NH2]/[COOH]≥6 wherein [NH2] (μ-equivalent/g) represents the amount of the terminal amino groups and [COOH] (μ-equivalent/g) represents the amount of the terminal carboxyl groups.

Le problème à résoudre dans le cadre de la présente invention est de proposer une résine polyamide semi-aromatique ayant une stabilité à l'arrêt, une résistance à l’eau chaude et une résistance aux produits chimiques élevées et également dotée d’excellentes propriétés d’adhérence et de compatibilité sur ou avec d’autres résines, ou analogues. La solution consiste en une résine polyamide semi-aromatique ayant des motifs dicarboxylate, dont 50 à 100 % en moles sont des motifs dicarboxylate aromatiques, et des motifs diamine, dont 60 à 100 % en moles sont des motifs diamine aliphatiques ayant de 9 à 13 atomes de carbone. Dans la résine, au moins 10 % des groupes terminaux présents dans la chaîne moléculaire sont coiffés en extrémité avec un agent de coiffage, tandis que la quantité de groupes terminaux amino présents dans la chaîne moléculaire s’inscrit dans la gamme allant de 60 µ-équivalents/g à 120 µ-équivalents/g (valeurs limites incluses) et répond à l'équation : [NH2]/[COOH] ≥ 6, dans laquelle [NH2] (µ-équivalents/g) représente la quantité de groupes terminaux amino et [COOH] (µ-équivalents/g) représente la quantité de groupes terminaux carboxyle.
