Five new optically active polyamidcs were synthesized at high temperatures by the condensation of the salts from L-tartaric acid with diamincs. The influence of polymerization condition on the specific rotation was discussed. Based on the specific rotation,'H-NMR, CD, IR, these polyamides were found to exist in ordered conformation other than one-handed helix. Moreover, the ordered conformation was quite stable according to the plot of specific rotation versus tempertature. The primary investigation showed polyamides...

Effects of the catalyst preparation and reaction conditions of oligomerization on naphthalene conversion were investigated in detail. The results indicated that Lewis acid intensity was the basic factor which influence naphthalene conversion. In addition, acid quantity and reaction conditions also influenced naphthalene conversion remarkably. Compared with condensation of naphthalene at high temperature (>500℃), naphthalene oligomerization catalyzed by SO 2- 4/ZrO 2 solid superacid showed great advantage....
