説明
Piperazine polyamides were prepared from piperazine and dicarboxylic acid (adipic, suberic, sebacic, terephthalic and isophthalic acid) by interfacial, low-temperature solution and melt polycondensation methods.<br>Polymers thus prepared have fairly low moisture regains. Polyamides from suberic and sebacic acid were hot-pressed and subjected to dynamic mechanical measurement. Temperature of tan δmaz of these polymers is found at around 100°C, which is relatively high in comparison with nylons, and does not shift appreciably by water absorption, which probably is due to the vaporization of water during measurement, but small shoulder appeares at 40_??_50°C in tan δ curve.<br>These moisutre absorption and dynamic mechanical behaviors are discussed in relation to the characteristic structures, such as the lack of N-hydrogen atom and the rigidity of piperazine ring.
