    摘要: There are disclosed and claimed novel polyamides showing transparency and other excellent properties, and the process for making them. The polyamides of the invention are prepared in the known manner and under common conditions by poly-condensing meta-xylylene diamine, which may optionally be partially substituted by para-xylylene diamine, at least one straight chain aliphatic diamine, at least one unsubstituted aromatic dicarboxylic acid and at least one aliphatic saturated dicarboxylic acid.

    摘要: There is disclosed a process for the preparation of novel transparent polyamides with improved properties. These polyamides are obtained by polycondensing 1,3-bis-(amino-methyl)-cyclohexane, which can be partly substituted by the 1,4-derivative, at least one aromatic dicarboxylic acid and at least one amino-carboxylic acid or the lactam thereof with at least one aliphatic straight chain or branched diamine or/and at least one aliphatic straight chain or branched dicarboxylic acid.
