低聚GAP中引发剂残基的结构鉴定及其残余氯分析
Structure Identification of Residual Group of the Initiator of GAP with Low Polymerization Degree and Its Residual Chlorine Analysis
摘要
Abstract
To determine the residual chlorine content in the industrial grade glycidyl azide polymer (GAP) with unknown part structure ,the GAP without chlorine(GAP‐P) was prepared by sufficient azido reaction of industrial GAP with low pol‐ymerization degree(GAP‐R) .The fine structural analyses of GAP‐R and GAP‐P were performed by electrospray ionization‐quadrupole‐time of flight mass spectra (ESI‐Q‐TOF‐MS) ,quantitative 13 C nuclear magnetic resonance spectra (quantitative 13 C NMR) and Fourier transform infrared spectra (FT‐IR) .The analytical methods of the residual group of the initiator , the residual chlorine content ,chlorine atom position ,the average polymerization degree and the number average molecular weight of GAP‐R were determined .The results show that the residual groups of the initiators of GAP‐R are the propylidene groups ,and the residual chlorine atoms are on the internal structural units ,the chlorine content is 3 .39% ,the average de‐gree of polymerization is 3 .70 and the number average molecular weight is 439 .57 g/mol .关键词
