FTIR Studies of Doped PMMA ‐ PVC Blend System

Abstract

The IR spectroscopy study shows miscibility between PMMA-PVC blends due to hydrogen bonding between C¼O of PMMA and hydrogen from CHCl of PVC. This blend system is doped by Camphor Sulphonic Acid (CSA) in the entire composition range. The doping of CSA in PVC, in PMMA and in PMMA-PVC blends shows changes in FTIR spectra. The interaction between PVC and CSA is through hydrogen bonding between C¼O of CSA and CHCl of PVC. Doping PMMA with CSA, indicate an interaction between H þ ion of CSA and oxygen atoms of C¼O and -OCH 3 of PMMA. Whereas in PMMA-PVC blend interaction between H þ ion of CSA and oxygen atom of C¼O of PMMA.

Preparation and characterization of functionalized poly(vinyl chloride) membranes for selective separation of perchlorate from water

“…Similar FTIR spectra of PVC membranes have been observed [49,50]. It has been reported [51] that the shift of the vibration signals from the organic acids functionalized PVC membrane were resulted from the interaction between the organic acids and PVC.…”

Surface studies of UV-irradiated poly(vinyl chloride)/poly(methyl methacrylate) blends

“…Miscibility in this system can be explained by interactions occurring between carbonyl group of PMMA and hydrogen atom from H-C-Cl group of PVC (hydrogen bond), or between carbon atom from carbonyl group of PMMA and chlorine atom from Cl-C-H group of PVC (dipole-dipole interaction) [16][17][18][19][20][21][22][23].…”

Reaction of carbon tetrachloride with methane in a non-equilibrium plasma at atmospheric pressure, and characterisation of the polymer thus formed

“…The C-Cl stretching vibration is characterised by the broad peak from 650 cm -1 to 800 cm -1 [35][36][37][38].…”

“…The peak at 1260 cm -1 corresponds to a C-H bending vibration from a chlorinated alkane species such as CHCl [36][37][38][39], while the peak at 1585 cm -1 is indicative of a C=C stretching vibration from an aromatic species. The peak around 1726 cm -1 is most likely due to a C=C stretching vibration from a substituted alkene species, but may also be an artefact, M a n u s c r i p t 16 due to residual THF in the polymer [39].…”

“…The peak around 1726 cm -1 is most likely due to a C=C stretching vibration from a substituted alkene species, but may also be an artefact, M a n u s c r i p t 16 due to residual THF in the polymer [39]. The C-H stretching vibration from CH 2 groups exhibits its signature at about 2960 cm -1 [35][36][37][38] Based on these data, it is evident that the result obtained from the FT-IR analysis is in good agreement with the conclusion drawn from NMR analysis.…”
