用紫外可见光谱法表征了不同来源的聚氯乙烯树脂(PVC)的热稳定性,用一氯化碘加成法测量了PVC的总的双键含量,用红外光谱法测量了PVC的孤立双键和共轭双键的相对含量.结果表明,PVC在加工期间的初期着色行为和长期热... 用紫外可见光谱法表征了不同来源的聚氯乙烯树脂(PVC)的热稳定性,用一氯化碘加成法测量了PVC的总的双键含量,用红外光谱法测量了PVC的孤立双键和共轭双键的相对含量.结果表明,PVC在加工期间的初期着色行为和长期热稳定性并不直接相关,前者取决于PVC分子链中共轭双键的含量。 展开更多

Poly-(N-vinylcarbazole) (PVC_z)-2, 4, 7,-trinitrofluorenone (TNF) charge transfer complex which is used as a photoreceptor, has been widely studied in its various aspects. So far as we are aware, there are only a few papers in the literature concerning its non-ohmic steady-state conduction. The study of the volt-ampere characteristics is valuable to the understanding of its conduction mechanism. 展开更多
