Abstract

The polyamides, which are heat resistant, have unit formulas (where A is R is or x and y are NH-, O-, S-, N-, N(CH3)- or N(C2H5)-; Z is N or C). They form high strength fibres/foil or high modulus of elasticity. They have specific viscosity 2-20 and a homogeneous crystalline structure. They are prepd. by polycondsn. of 2,5-/2,6-/2,7-napthalene dicarbonyl chloride with a diamine: H2D-AR-NH2 in polar solvent.
