A series of novel polycyclic aliphatic polyamides was synthesized by direct polycondensation of the 1,6-diamantane dicarboxylic acid with various alicyclic diamines in N-methyl-2pyrrolidone (NMP) containing lithium chloride, using triphenyl phosphite and pyridine as a condensing agent. The polyamide

A series of new polyamides were synthesized by direct polycondensation of the 1,6-bis(4-aminophenyl)diamantane with various dicarboxylic acids. The soluble polyamides had high inherent viscosities, ranging from 0.73 to 1.21 dL/g. Polyamides derived from 5-tert-butylisophthalic acid and ( {)-1,3-cycl
A series of new polyamides 3 were synthesized by direct polycondensation of the 1,6-bis[4-(4-aminophenoxy)phenyl]diamantane (1) with various dicarboxylic acids. The polyamides had inherent viscosities of 0.45-1.90 dL/g and number-average molecular weights (M n ) of 24,000 -110,000. Dynamic mechanica
