| titleOfInvention | PROCEDURE FOR OBTAINING TRANSPARENT POLYAMIDES. |
| abstract | Procedure for obtaining transparent polyamides by polycondensation of diamines, dicarboxylic acids and amino acids, or respectively their lactams, in the manner known per se and under the usual conditions, characterized in that: a) l, 3-bis- (aminomethyl) -cyclohexane or mixtures of 1,3-bis- (aminomethyl) -cyclobexane and l, 4-bis- (aminomethyl) -cyclohexane with the l, 3-bis- (aminomethyl) part rising.) cyclohexane at least 50 mol%, preferably 90 to 60 mol%, relative to the total amount of the diamine components; b) aromatic dicarboxylic acids containing 7 to 20 carbon atoms, preferably 8 to 14 carbon atoms, especially mononuclear and bearing carboxylic groups in the meta or para position, or mixtures of these dicarboxylic acids, and c) aliphatic aminocarboxylic acids with up to 20 carbon atoms, preferably 4 to 12 carbon atoms, especially -aminocarboxylic acids, or their lactams, the part of the amino carboxylic acids or of the lactams rising to 5 to 60% by weight, in relation to the total weight of the polyamide.
