摘　　要：聚萘是一种新型的高分子,掺杂后具有导电性能,是一种导电聚合物。本文用裂解色谱法(PGC)研究了它的热裂解行为,分离鉴定了主要和特征裂解产物,并在此基础上,对其分子链结构和裂解机理进行了讨论。 实验部分 (一)样品 聚萘(PN):由本实验室直接从萘合成,使用前在100℃下真空热处理48小时加以提纯。 (二)仪器和实验条件 裂解器:美同CDS Py-ro-Probe 190型(丝式);裂解温度300-800℃,裂解时间5s。色谱仪:北分厂-2305E型。The behavior of thermal degradation of poly-naphthalene (PN) was investigated by using pyroly-sis-gas chromatography. The main products were separated and identified in the pyrolysis temperature range from 400-800℃. On the basis of the distribution of main products, the pyrolysis reaction of PN was considered as the random rupture reactions and the structures of molecular chains were discussed.
