【摘要】 <正> 自从白川英树等合成聚乙炔(PA)膜,并用电子受体或给体掺杂使其变为P型或n型半导体之后,近年来对PA的合成、结构及性能进行了大量研究,但采用PGC法对PA热裂解反应的研究,只有为数不多的报道。本文介绍了热异构化前后的稀土(Ln)和钛(Ti)两体系合成的PA的热裂解反应,提出一个适于比较两体系PA的参数,并观察了

【Abstract】 This paper describes the pyrolytic reaction of polyacetylene (PA) prepared with titanium and lanthanide elements based catalyst systems before and after thermo-iso-merization by PGC. A parameter suitable to compare difference in molecular structure of PA’s has been suggested and applied to study. Under the given pyrolytic conditions, cis- and trans-PA showed quite similar pyrogram. A smallr change in h1/h5 ratio has been found for Ln-PA than that for Ti-PA with the increase of aging time. These results demonstrates that Ln-PA has better agnig property than Ti-PA.
