摘要:
Copolyamides with improved properties are obtained by polycondensing aliphatic and/or aromatic dicarboxylic acids with an amine mixture of diaminodicyclohexyl methanes and optionally homologous polycyclohexyl polyamines and one or more aliphatic diamines, said copolyamide being useful for the production of shaped articles such as films, sheets and injection moldings.
