摘要
采用中红外(MIR)光谱(包括:一维、导数及去卷积MIR光谱)分别开展了聚氯乙烯分子结构研究.实验发现,聚氯乙烯分子结构红外吸收模式主要包括νC-H、νasCH2、νsCH2、δ CH2、βC-H、γC-H、νC-C、ωCH2和νC-Cl.聚氯乙烯分子结构的去卷积MIR光谱的谱图分辨能力要优于相应的一维及导数MIR光谱,可以提供更多晶体/非晶体结构相关的光谱信息.
Abstract
The molecular structure of polyvinyl chloride was studied using mid infrared(MIR)spectroscopy(including one-dimensional,derivative and deconvolution MIR spectroscopy).The experiment found that the infrared absorption mode of polyvinyl chloride molecular structure mainly includes νC-H,νasCH2,νsCH2,βC-H,γC-H,νC-C,ωCH2 and νC-Cl.The spectral resolution of deconvolution MIR spectra of polyvinyl chloride molecular structures is superior to the corresponding one-dimensional and derivative MIR spectra,which can provide more spectral information related to crystalline/amorphous structures.
