Abstract
Polyamides are prepd by reacting (I) cycloaliphatic diamine isomers of formula I, opt. mixed with 6-20C aromatic diamine, 2-20C (cyclo)aliphatic diamines or 7-20C araliphatic diamines, and (II) 2-20C (cyclo) aliphatic dicarboxylic acids, opt. mixed with 2-20 C aminocarboxylic acids or their lactams. (where R is H, methyl or ethyl, A1 is NH2CH2 and A2 is H, or A1 is H and A2 is NH2CH2; and A3 is NH2CH2 and A4 is H or A3 is H and A4 is NH2CH2). The polyamides are transparent and have good mechanical and electrical properties at relatively high temps.
