The present invention relates to amorphous transparent copolyamides of formula: PACM.T / D.X / X1.Y1 resulting from the condensation of PACM, terephtalic acid, a diamine D, a diacid X, a diamine X1 and a diacid Y1 in which :
PACM denotes the p-bis(aminocyclohexyl)methane,
T denotes terephtalic acid,
D denotes a diamine chosen from aromatic, arylaliphatic and cycloaliphatic diamines,
X denotes a diacid HOOC-(CH2)n-COOH having from 8 to 20 carbon atoms,
X1 denotes an aliphatic diamine,
Y1 denotes a diacid HOOC-(CH2)n-COOH having from 6 to 20 carbon atoms,
the mol proportion of PACM.T is such as (PACM.T)/(PACM.T+D.X) is above 0.5, and can be increased to 1,
the mol proportion of X1 is between 16% and 38%,
X1.Y1 can be replaced partly or totally by Z, a lactam or an alpha-omega aminocarboxylic acid, having from 9 to 20 carbon atoms, and in this case the mol proportion of Z is between 33% and 75%.
本发明涉及式如下的无定形透明共聚多酰胺:PACM.T / D.X / X1.Y1 由 PACM、对苯二甲酸、二元胺 D、二元酸 X、二元胺 X1 和二元酸 Y1 缩合而成,其中:
PACM 表示对双(氨基环己基)甲烷、
T 表示对苯二酸、
D 表示二胺,选自芳香族、芳脂族和环脂族二胺、
X 表示具有 8 至 20 个碳原子的二元酸 HOOC-(CH2)n-COOH、
X1 表示脂肪族二胺、
Y1 表示具有 6 至 20 个碳原子的二元酸 HOOC-(CH2)n-COOH、
PACM.T 的摩尔比例为(PACM.T)/(PACM.T+D.X)高于 0.5,并可增至 1、
X1 的摩尔比例介于 16% 和 38% 之间、
X1.Y1 可以部分或全部被 Z 取代,Z 是一种内酰胺或α-ω 氨基羧酸,具有 9 至 20 个碳原子,在这种情况下,Z 的摩尔比例在 33% 至 75% 之间。
