Title (EN) LIQUID CRYSTALLINE POLYESTER RESIN COMPOSITION
(FR) COMPOSITION DE RÉSINE DE POLYESTER CRISTALLINE LIQUIDE
(JA) 液晶性ポリエステル樹脂組成物
Abstract: front page image
(EN)Disclosed is a liquid crystalline polyester resin composition having good mold releasability during molding, which is further improved in heat resistance. Specifically disclosed is a liquid crystalline polyester resin composition which is obtained by blending 0.001-1 part by weight of a fatty acid ester into 100 parts by weight of a liquid crystalline polyester resin. The fatty acid ester is a tetraester of pentaerythritol and a higher fatty acid having 10-32 carbon atoms, which has an acid value of 0.01-0.5 and a hydroxyl number of 0.01-5.
(FR)L'invention porte sur une composition de résine de polyester cristalline liquide ayant une bonne aptitude au démoulage lors du moulage, qui est encore améliorée en ce qui concerne la résistance à la chaleur. De façon spécifique, l'invention porte sur une composition de résine de polyester cristalline liquide qui est obtenue par mélange de 0,001-1 partie en poids d'un ester d'acide gras dans 100 parties en poids d'une résine de polyester cristalline liquide. L'ester d'acide gras est un tétraester de pentaérythritol et d'un acide gras supérieur ayant 10-32 atomes de carbone, qui a un indice d'acide de 0,01-0,5 et un indice d'hydroxyle de 0,01-5.
(JA) 本発明は、成形時における金型との離型性が良好で、耐熱性が更に改良された液晶性ポリエステル樹脂組成物を提供する。詳しくは、液晶性ポリエステル樹脂100重量部に、ペンタエリスリトールと炭素数10~32の高級脂肪酸とのテトラエステルであって、酸価が0.01~0.5、水酸基価が0.01~5である脂肪酸エステル0.001~1重量部を配合する。
