Title
(EN) SEMI-AROMATIC POLYAMIDE RESIN AND METHOD FOR MANUFACTURING SAME
(FR) RÉSINE DE POLYAMIDE SEMI-AROMATIQUE ET SON PROCÉDÉ DE PRODUCTION
(JA) 半芳香族ポリアミド樹脂、及びその製造方法
Abstract
(EN)
A semi-aromatic polyamide resin which has excellent heat resistance and heat discoloration resistance, and whereby mold staining due to outgassing during melt molding can be suppressed, the semi-aromatic polyamide resin also having excellent melt fluidity and gelation characteristics, wherein the semi-aromatic polyamide resin contains a constituent monomer obtained from hexamethylene diamine and terephthalic acid, and a constituent monomer obtained from 11-aminoundecanoic acid or undecane lactam, the relative viscosity (RV) thereof is in the range of 1.95-3.50, and the relationship of the terminal amino group concentration (AEG), the terminal carboxy group concentration (CEG), and the concentration of terminal amino groups blocked by a monocarboxylic acid (EC) satisfies a specific formula.
(FR)
L'invention concerne une résine de polyamide semi-aromatique qui présente une excellente résistance à la chaleur et à la décoloration thermique, et permet d'éliminer les taches de moisissure dues au dégazage pendant le moulage par fusion, la résine de polyamide semi-aromatique présentant également d'excellentes caractéristiques de fluidité en fusion et de gélification. La résine polyamide semi-aromatique contient un monomère constitutif obtenu d'un hexaméthylène diamine et d'un acide téréphtalique, et un monomère constitutif obtenu d'un acide 11-aminoundécanoïque ou d'un undécane lactame, la viscosité relative (RV) de celle-ci se situant dans la plage de 1,95 à 3,50. La relation entre la concentration du groupe amino terminal (AEG), la concentration du groupe carboxy terminal (CEG), et la concentration des groupes amino terminaux bloqués par un acide monocarboxylique (EC) satisfait une formule spécifique.
(JA)
耐熱性と耐熱変色性に優れ、さらには溶融成形時のアウトガスによる金型汚れを抑制でき、溶融流動性、ゲル化特性に優れた半芳香族ポリアミド樹脂であって、ヘキサメチレンジアミンとテレフタル酸から得られる構成単位、及び11-アミノウンデカン酸又はウンデカンラクタムから得られる構成単位を含有し、相対粘度(RV)が1.95~3.50の範囲であり、アミノ基末端濃度(AEG)、カルボキシ基末端濃度(CEG)及びモノカルボン酸でアミノ基末端を封鎖した末端濃度(EC)の関係が特定の式を満たす半芳香族ポリアミド樹脂である。
