| Five functionalized polysiloxane polymers containing phenol, 2-fluorided phenol, 3-fluoro phenol, 2,3-difluoro phenol , 3-methyl fluoro phenol, respectively, have been synthesized and estimated for analysis of the influences of those functional groups on the polymers' sensitivity to dimethyl methyl phosphonate(DMMP). The experimental results shows that those fluoro phenols with stronger hydrogen bond acidity, however, provide smaller sensitivity, compared to phenol. Infrared spectroscopic analysis indicates that forming hydrogen bond of fluorine atom and hydroxy is the reason of increasing the sensitivity and that intermolecular hydrogen bond can make a larger decrease of sensitivity than intramolecular one. |
