✦ Synopsis


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 polyamides had inherent viscosities of 0.33-0.49 dL/g. The glass transition temperatures of the these polyamides were in the range of 2O0-22O0C, and the 5% weight loss temperatures were in the range were 290-319Β°C in nitrogen. 0 1995
