This work shows how laser-Raman spectroscopy can be applied in cases where a combination of an efficient, relatively inexpensive, simple, and nondestructive technique is desirable for the determination of the monomer content in poly(methylmethacrylate), PMMA. The method has been initially applied in order to investigate the optimum conditions for the in situ polymerization of PMMA in the pores of silica sol-gel for the purpose building a solid state dye laser. The calibration line which converts the ratio of two Raman intensities in the PMMA spectrum (at 1640 and 1725 cm(-1)) into percentage of monomer content, under the current experimental conditions, has been achieved on the basis of NMR spectroscopy. In addition, it is shown in this work how Raman spectroscopy can allow for the estimation of the reaction enthalpies of partial monomer to polymer conversion after thermal treatment at different temperatures and periods of treatment. |
